(See updates at bottom of original review)How many times have you bought a product online after extensive research only to find when it's delivered it doesn't live up to the hype? I'm naturally suspicious reviews that are not verified purchasers or revised who are given free or discounted merchandise to provide a "free and unbiased review" are shills for the manufacturer or retail seller. Well, none of these app!y here. And, my review is unaffiliated with the seller or manufacturer.This item is everything users claim. I have tested on one long drive and the resulting video and audio were of excellent quality, the field of view was satisfactory, the automatic iris adjusted for varying light levels from bright sunlight overhead to low ambient light at sundown. I'm very fastidious about video quality as a 40-year veteran of audio-visual enterprises. I won't attempt a technical review as most potential buyers are interested in key features and whether the device works reliably and has any downside or limitations. Surprisingly small, it is relatively easy to set up once you've installed a micro-SD class 10 card. 32gb is best because any video file is big, and these are hi-definition. Throw away the small, inadequate instruction booklet included in the box, and go to the rexingv1.com site and download and print the more detailed, comprehensive update. It's well worth it. Can't comment on reliability until I've used it more over time, but it seems well-built yet I worry exposure to the notorious Florida high ultraviolet light content in unremitting sunlight might take a toll. Another tip. I installed my unit using Velcro tabs until I'm sure of the device and it proves reliable. Just DON'T fail to use alcohol on a microfiber towel to clean the installation area (behind the mirror) before attaching the 3M tab supplied or Velcro. This will better assure the adhesive won't come loose from high windshield temperatures. You won't be disappointed by the high quality images. They are standard .mov files. I haven't tested the parking feature or motion detection features and because they require accessing the menu selections, I expect few will use them, except in cases where theft and damage incidents in their communities warrant their use. The limitations I found included the power cord, while long, required some compromise because it isn't quite long enough for the run from mirror to lighter plug-in on my Honda Odyssey. Another added foot would have been perfect. The 3M adhesive pad is permanent and will be destroyed if you attempt to remove it. Two pads included for this price are not ideal if you plan to use the device in multiple cars or you make a poisoning mistake on first try, as I did. I mounted it to be unobtrusive, hidden mostly by the mirror. But, windshields reflections from attached GPS unit or cellphone cast shadows in the Rexing unit's camera's field of view. In summary, this dashcam is the best I found after review and research of more than a dozen I seriously iinvestigated from a long list of Amazon offers. It is easy to install, set-up and operate, complete with a tilt-adjustable lens for the perfect balance of panorama and horizon, produces high quality images and audio, and is lightweight. 4 1/2 stars.UPDATE: 12/15/2015Measure a seller not just the product but also by the after-sales support. I bought two of these dashcams, and installed one. The other is a Christmas gift and we'll soon know if my experience will be repeated. So far, this little device has performed superbly. If you want to move it to other cars you own, you need additional strips of adhesive and the attachment plate. As other customers have noted, Velco tabs CAN be used, but only until the heat builds on the windshield and you find the dashcam hanging by the power cord. One email to Rexing did the trick and my request was met with quick dispatch of extra adhesive strips via first-class mail. This is the way to stand behind a great product. Let's hope Rexing continues that winning philosophy because if/when the item experiences a problem, and is out of Amazon 30--day warranty, buyers still influence potential buyers based on their experience, called "back-end sales". Already, I've recommended this product to friends and family. I'll update this when the second unit is installed. ( My only improvement recommendation is to add another plate and 3M adhesive strip to the product package and lengthen the power cord by a foot. And, a tip to future buyers. Clean the installation area on the windshield glass with alcohol beforehand)Update: 2/22/2016. I liked the quality..and customer service of the first well, so well, l decided to buy another and it functions as well as the first. As a backup, I just requested Rexing supply me with extra adhesive tabs. The tabs that came with the unit are about as sticky as any but, they are destroyed by extreme heat because Florida sun has a high UV content and you want to have extras on hand. I had positioned my first tab to high on the windshield and could not remove the unit without major effort. In so doing, If you are lucky enough not to destroy the tab, it can't really be reapplied. I tried it and it lasted until the cloudy winter weather turned to sunshine and higher near 85 degree temperatures. Then, the unit fell off, caught only by the power cord. Glad I had extras on hand. I've suggested to Rexing that offering extra adhesive tabs for a modest cost would a good idea because buyers sooner or later will need to replace the original ones for their V1.Tip of the cap, Rexing. Keep up the good customer support. Consequently, I've upped my rating to 5-stars as a satisfied and verified buyer.UPDATE: 6/7/2016After the allure fades, some electronics develop issue or problems due to inherent flaws or use. Here is my experience after 7 months of use for one V1, and 6 month for the other. Again, as a reminder, the high UV content and heat of the Florida sun will zap, degrade, deteriorate almost anything over enough time. Anything exposed to sun, form PVC, plastic pool liners, car dashboards, paint, home siding, you name it. Some, when I bought these V1 models, I knew to be skeptical that they would last, as consumer electronics are not built to fully withstand direct sun exposure on windshields or interior heat build-up when you park your car. Surprise. Neither show any problems. The video and audio still function as new, and the cameras and housings look factory-new, with no plastic curdling or dimpling from heat or direct sunlight. In fact, a review of video files of my wife's month long trip from Florida to Tennessee and on to South Carolina to see her mom, and a stop to see our grandchildren were a perfect record of her daily travel. One downside, however, which I have addressed to Rexing. The adhesive tabs don't hold up to the heat and UV I described. Yet, when applied, the 3M tape is very sticky and adheres well. Just try talking it off, and you'll understand. But, in time, they seem to dry out and become less tacky, and the weight of the V1 - although slight - causes it to come loose, and you find the V1 dangling by its power cord. So far, this effect seems to only result from abnormally hot summers and mostly in Southern states, and could be a factor when a buyer is looking at competing models. To its credit, Rexing has willingly, quickly replaced the tabs with new ones. If this experience continues to occur ever 4 months, it could become a tedium. My cost-benefit analysis tells me the performance of the V1 far outweighs the small aggravation of replacement of the tabs, and buyers affected are not all in Florida. This all depends on the goodwill of Rexing, until a better 3M adhesive can be found.UPDATE 5/21/2017Well, the good folks at Rexing have taken my suggestion (and I'm not alone) to heart and added a windshield mount that we hope will solve the only real liability I complained about regarding my first purchase, which is the adhesive tape mount won't hold up in hot climate, high UV sun states such as Florida.).Rexing, listening to customers pays off as I just bought my third V1 and tried it out with the windshield suction mount during a central Florida to Baltimore and return 2,000 mile trip. Result? Perfect performance for both. That's saying a lot due to the unbelievable potholes, unpacked rough pavements of Baltimore streets, the pothole kingdom. (If I was forced to live and work in Baltimore, I'd start a wheel alignment business.Baltimore streets are a series of potholes with just enough surrounding asphalt for aesthetics).The windshield mount never came loose from the bumps or tire shock. And the V1 performed like the others. Clearly, if you purchase the V1, buy the economically-priced windshield mount.For those unsure which grand to buy, let me save you time. I was determined to find the best on the market in this price range and spent hours reading reviews of the boiled-down list I compiled of devices with compelling features. I read almost all the reviews. There were downsides and reliability and resolution issues with them all. Those with crisp resolution in daylight couldn't match it in low ambient light levels. Some were balky in recording files to the storage card, others quit working after a short period. I wanted a new purchase that would swivel 180 degrees, but even the best were had class.So, I gave up looking. For my basic purpose, I knew from experience I couldn't do better than the Rexing V1. Experience and sustained performance of my two others clinched my decision. And, the new mount made it all the more a great choice. Unplanned to get two new mounts for the other devices. By the way, I didn't have time to check on a firmware update, and I'm in no hurry given the V1 performance out-of-the-way.UPDATE 11/27/2017:What you buy when you purchase from Rexing: Peace of Mind that they will stand behind their products.One of my V1 dash-cams failed. The battery became defective, as it turned out, and would cycle on then off, crashing the device and eventually corrupting the micro-sd card and not allowing the camera to show any video even when connected to power. When powered on, only black appeared in the display screen. I removed the card and reformatted it in one of my other V1s, which rehabilitated use of the card. When connected to power through a PC, I tried upgrading the firmware in case that was a solution. Now, the defective V1 showed video using the built-in camera, but the low battery icon showed a red "X", and a message, "low battery" although I had followed Rexing's instructions to try to charge it for at least 3 hours. But, the battery icon still showed the red X and when the V1 was disconnected from my PC to operate on battery power, it displayed the "Red X", and crashed from low battery.Not to worry. I would not be stuck with a defective unit. After contacting Rexing, they requested I attempt the long charge, and if the unit still failed to operate, they promised a replacement wold be immediately mailed to me. Good to their word, it arrived and it works perfectly. Rexing even supplied a postage-paid label to return the defective unit.After recently checking to see if there is another brand device which produces better video and still is as unobtrusive on the windshield as the V1, I'm happy to report, the V1 is still superior. In those cases with so much competition, positive reviews are crucial to help potential buyers make the best choice and Rexing knows it.So, bottom line? Rexing sells the dash-cam with the best resolution and has probably the best reviews because not only is the unit superior, but so is its customer support. And, after purchase, that becomes the biggest factor associated with your purchase, reliability and support in those cases when things go wrong. (By the way, the touble-shooting on the Rexing website is very helpful)

Easy to install and use. I connected it in our RV using the optional wiring. It was easy, and hiding the wires was even easier. Used it on our first trip this past month and had no issues. Lies flat against the windshield and provides a fantastic picture. Great for flat windshield RVs and other vehicles.

I always have a dash cam in my car to help my case in the event of a crash. I also always have one for entertainment purposes, to capture bad drivers on video for my “Bad Drivers of Napa Valley” Youtube channel. And recently I needed to update my dash cam set up so I did some research and saw that the Rexing V1 was Amazon's best seller along with the nearly 5 star rating. I decided to purchase this camera and get a SanDisk class 10 high speed memory card to use in the camera.The camera arrived and it was time to unbox it and have a look. The camera was packed very well and the camera's build seemed sturdy and light. The buttons are nice and solid and don't rattle. The user manual is very well-written and easy to follow. It was a snap to set up in the car and the cord is nice and long for larger vehicles. I went through the camera's menu items to program all the settings the way I wanted them. That was easy too.I went for a drive to test it out and then came home to review the footage. Connecting it to the computer, the computer immediately recognized the camera and I opened up the folder. Soon after connecting the camera to the computer, the camera powered itself off and interrupted the file transfer. How strange. I later discovered that this is due to a camera setting. The 'Auto Power Off' setting was the culprit. I simply turned it off and the camera stayed on the entire time it was connected to the computer. The auto power off feature is there so that the camera will shut itself off if left on, but not recording, after whatever time you set it for.Reviewing the footage, it looks great for a camera in its class. The image is fairly sharp, clear and in focus for the entire frame, with minimal chromatic aberration at the edges. Colors look really good but very slightly washed out in certain contrast and exposure scenarios. Still acceptable for a camera in this class. It handles contrast and exposure exceptionally. Going from deep shade under tree canopies to bright sunny open skies and vice versa, the camera does a great and quick job at adjusting exposure back and forth between vastly different lighting. It should be noted that this camera compresses the footage a lot, as do just about all dash cams in this class. So there is some compression artifacting (blocking) in scenes with low contrast or expansive shaded areas. For a camera in this class the video still looks great.The audio is about what one would expect from a camera like this. The sound is good, but not as great as the audio on a typical consumer grade camcorder. But good enough for a dash cam.The first few days of owning this dash cam there was no rattling sound when driving over bumps and rough pavement, but it has developed a little bit of a light rattle. This can easily be fixed by sandwiching a layer of fabric or two, between the camera body and the mount. Just be sure and cut the square out from the middle of the layer(s) to the correct size where the mounting tip inserts into the camera. One dash cam manufacturer that sells a camera with a similar shape, ships a foam pad along with the camera to remedy the inherent rattle with these types of mounts. I think Rexing and other sellers of these wedge shape cameras should do the same.So that evening I decided to purchase another Rexing V1 for my spouse's car, since I liked the first V1 so much. But this is where things get interesting. Naturally I expected the quality of the subsequent purchases to be on par with the first one. I was wrong.The second camera arrived in the same well-packed fashion and I excitedly got it set up with identical settings and went for the test drive. I came back and analyzed the footage. Something seemed off. I pulled up footage from the first V1 to compare. I had driven the exact same route with the same lighting conditions as before, so I could get an accurate comparison. This second camera's video footage was blurry in the outer 5th of the video frame, on both sides, along with more chromatic aberration. I couldn't read license plates even when right next to them, unlike with the first V1 purchase. The lens was perfectly clean, as I was very careful not to touch it. The camera also rattled very badly from the very first use, but once again fixed with a layer of fabric between the camera and mount. The audio also had a rhythmic zapping noise about every second, which is a very common problem among budget dash cams. This issue was not present with the first V1. In both V1's I was using the same high quality memory card, and the cameras plugged directly into the DC socket, not into a splitter.Disappointed, I returned that one through Amazon and ordered a replacement and thought the dud was just a fluke.The replacement came (my third V1 purchase) and this one was in better shape, but still problematic. It didn't have that horrible zapping noise or the rattle at all, thankfully. But this time the video was blurry on the whole right 1/4th of the video frame, which is still unacceptable. I've never had this problem with the G1W which is half the price. (Though if your camera is crisp throughout the frame I find the V1 footage to be overall better than the G1W). So instead of returning this one through Amazon I contacted the company to let them know of the issue and see what advice they might have for me. They quickly replied, apologized and offered to exchange it for another replacement camera directly through their company. Their customer service seems great so far.The replacement camera of the other replacement came very quickly and I tested it out. So this 4th camera I got from them passed my test with flying colors. This one has super sharp video in all parts of the frame and there are no problems with it. I love it just as much as the first one I bought from them. I only took one star off the review because of the two defective units. They get big props for their excellent, responsive and efficient customer service.Some tips for those purchasing this camera:Turn off gravity sensing. Numerous owners complain that their cameras shut off randomly while recording. A major culprit is said to be the gravity sensing option being turned on. I turned mine off and have had no unexpected shutdowns.Use a good, class 10 memory card.Download and install firmware updates from the Rexing USA website.Try to avoid plugging this camera into a splitter for DC outlets, as this is said to sometimes cause the zapping noises in the audio I mentioned. The zapping sounds can also sometimes be caused by sub-par memory cards or possibly a defective power plug.Try the fabric trick if your camera develops a rattle.Clean the glass really well before sticking the 3M double sided mounting tape to it.Try not to leave your camera in a hot car in the sun when you're not driving, during hot summer days.If your camera shuts off while connected to your computer, it is because the auto power off feature on your camera is enabled.I will keep this review updated.

I have used the Rexing dashcam for nine years without fail. I upgrade every three years, not due to any device issues, but because I like to have an extra for times I use rental car. I highly recommend the Rexing for the quality, and also the incredible customer service when I had questions with my first one.

Great product for the price. I like that it has an app associated with the camera. Connection was easy. The camera screen looks good and installing was easy. Definitely would recommend!

Bought this in 2019, still working great. Saved me thousands of dollars when I got hit by a bus and they paid for all the expenses. Would like some recommendations for Rexing front and rear cam?
