0.31in-50ft Dual Lens Endoscope

Like a lot of people, I bought one of those $30 endoscopes that require you to use an app on your phone to see the stream. Like a lot of people, I took an hour with it, threw in the towel, and shipped it back. This Teslong endoscope is the real deal. Yes, it's more expensive, but not prohibitively so and for that extra price you get a great picture, lighted dual-cameras (top and side), a sturdy, easy-to-use control unit, and generally good battery life. As soon as we broke it out, we went into the basement to thread it up through the floor to try to identify the source of a leak around the skirt of the tub in our 2nd bathroom. The multi-level light was up to the task of illuminating the darkened cavity and when we needed to sneak up around the side of the tub for a sides shot, the side camera performed well, helping us narrow down exactly where the leak was flowing. The one frustration I have, and it's not unique to this endoscope, is that the flex cable, while strong, still flexes a little too much when you are trying to aim a camera that is several feet away. Our solution was to find a piece of 1/4" PVC pipe that we had laying around, thread the camera up and in, tape the flex cable to the pipe to ensure it was not going to move when we twisted the pipe, and then use the pipe to rotate and aim the camera. This might not work in every situation, but it worked well for us. All in all, the Teslong "feels" like a piece of semi-pro gear, not like a piece of junk like the endoscopes in the $30 range. It's not a pro endoscope, and it lacks some of the resolution and other nice-to-have features of larger, handheld units, but it does the trick for the price. Highly recommended!

Disclosure up front, this is a solicited review, but honestly I wouldn't be writing it if I didn't believe they truly deserved it. This is an excellent home use endoscope for a very reasonable price. Presents a clear recordable image with a quality, easy to use interface. I really did not expect it to be as good as it is. There are some limitations to it, but used for the right purposes, it's a phenomenally powerful tool. Do understand that the camera has a fairly limited focal range (it really only sees very well about an inch to three inches in front of the camera) and the cable is bendable, but not controllable outside of your grip. What that means is that if you want to reach through a wall or some sort of constriction, and then look around at an open space on the other side, you're not going to be able to do that very well. But if you want to follow a tight pipe, or see a good distance into a very narrow channel, it's absolutely great for those applications. The unit arrived quicker than was forecast as I recall, and was very easy to use and understand right out of the box. One thing that can be a little disorienting is sorting out which way is actually up when you're scoping a pipe or channel, because the top of your screen is not necessarily the top of the camera. That's not a shortcoming of the equipment at all. I have had a few experiences lately where a company that produced a garbage product and had no customer service at all, then later tried to hold a refund "hostage" unless/until I would offer to change a negative review to a positive one. That is not the case here at all. I could not be happier with this endoscope and glad to be able to steer people toward it. Nice job Teslong!

This product is good and does the job well. I have no issues with it on that front. Picture quality is top notch, and brightness is awesome. The two things I'd change: 1. The cord needs a straight end- the last foot or 2 of the cord should probably be rigid, so it goes in the direction you point it. Because it's flexible, it goes all over the place, which is time consuming to manage. As a result, the other thing I'd change: 2. Some sort of zoom- it'd be nice to be able to zoom out of the picture to see better. I used this in the first floor ceiling of a 2-story house, and because of the space between the joists, I couldn't tell my relative bearing well. Trying to get it aligned to where I wanted to go was a pain, which if I could've zoomed out would've helped orient better. That said, the tool itself is good. 50 ft of cord goes all over, so make sure you can manage that. The only way you'll be able to really use the cord is to attach is to a fiber wire and let that lead the way. So opt for the shorter cord.

I do a lot of work on my older house, both as a hobby and to save money. This endoscope has saved me well more money than its cost in the first few months, and severely cut down on the "repairs" from exploratory holes I used to have to put in walls and ceilings. I am not a professional, so I don't use this every day, and I am pretty tech savvy, so the balance of features and usability versus technical knowledge to plug in, charge, and make it work was just right. The endoscope itself feels very solid, the screen is bright and clear, and the camera and light, with the ability to switch from the front to the side camera at the base of the unit (dual camera is great!), giving me good confidence in the longevity. The recording feature has been especially useful, as it captures the video from the camera, but the voice at the base. By narrating what I am doing and seeing on the camera, I can later replay the video either on the unit or at my desktop computer and easily understand what I was seeing. This has also been useful when later showing a contractor what they will expect to see when they tear into the walls! I don't have any real complaints, but I do wish I had bought a shorter probe length. I thought up front that buying a longer one than I needed (I bought a 16ft long probe) would "future proof" my needs. Well, the problem is that in all the uses so far, I haven't used more than the first 4 feet of the probe, and as such the extra 12 feet was curled up, making holding the base unit and the coil of extra probe while trying to manipulate the tip of the probe an exercise in patience and re-doing. That is not a dig on the device, but rather my choice in purchasing. The probe itself is flexible, but holds its shape well. Note that at this price point, the probe is like a microphone stand, you bend it and it stays that shape. It cannot be remotely manipulated once it is inserted into whatever you are looking at. Overall, this was money well spent, with a high quality device, nice case and accessories (mirror and magnet). I highly recommend!

I don't have any complaints with this purchase. I suspected I had a yellow jacket hive above the drop ceiling in my basement. I saw them flying in and out of a hole in the side of my house. I purchased this to stick through a hole in my drop ceiling to scout out the situation. The image quality was good for what I needed. It has three levels or brightness, but the lowest and middle brightness didn't seem too different to me. The cable was flexible enough to bend it and move it around, but firm enough to keep the shape and angle I needed. I didn't use the hook accessory that came with it. Case is nice and durable, which make carrying it around easy. The screen size was fine, the entire unit was smaller (but wider) than my old iPhone 7 Plus. I would definitely recommend this product. Oh, and if you were wondering, the yellow jackets were not above my drop ceiling after all, they were between my outside walls and the siding. Cost me more way more for the exterminator than it did for this Teslong endoscope camera.

if you leave your car in the sun the rubber cup keeps falling off. I clean the window and the rubber cup same thing too much sun will make it falloff. I would return but to late. camera is ok .

Have been using for almost 2 months now and still amazes me with the number of uses. Originally purchased to help run wiring inside walls and within 1st floor ceiling of a 2 story home. For those purposes it works flawlessly - I was able to see top plate penetrations and find my way through a vertical fireblock into a garage area. The depth of field was more than adequate, the light was bright and I could see obstacles clearly. Was also surprised that my stud finder could find the camera wire. For another project, I had to locate a pipe and had no trouble locating to open up the drywall to make a cut. One thing I did find helpful was to place markings every foot of the cord to help me gauge location within the ceiling. I was installing a cold air intake on my truck and dropped a quarter-turn plastic screw into the engine bay where it landed on a skid plate. With the endoscope I was able to quickly locate it and push it onto the garage floor. Overall - a great tool for the money and excellent value - 1080p / great picture and built-in screen is perfect size - love that I can remove the SD card and download to a PC quickly rather than wirelessly or via a phone - dual camera works well and like that can be flipped back and forth without the need for adapters which can fall off - rugged case and easy to use controls - case and accessories are top-notch - have not had a chance to need yet, but waterproofing is a nice to have I previously used another brand/model that required connecting to a phone, which I thought would be better, but did not like the quality, a cumbersome process of saving videos (no removable card) and requiring me to use my phone on ladders, crawl spaces, attics, etc.

I was impressed with the video quality and the length of the camera. Worth the buy
