Holy 💩…
Just.. WOW. I really am amazed, astonished, astounded!!! Ok so I have a she-shed I spend most of my time in, in the back yard that’s mostly built around my cats. Therefore I need to leave the door open so the furballs can get in/out. (Pictured: my setup and how I have the curtains at night) This then invites an insane amount of mosquitoes in and everyone is getting eaten alive including me. I professionally spray, i fog, I have bug zappers, those tube things and dunks and I’m still covered in bites. I have to dress head to toe, sweating my tuckus off and any peaking skin gets decimated. I didn’t want to try this at first because it’s so expensive and refills only last a small amount of time but holy crap you get you pay for!!!! -First night: it had just rained heavily and was hot and humid so I expected heavy demon fire. There were already mosquitoes in the shed when I placed it at dusk.. ready for war. Prepared to run around like a crazy person armed with my electric swatter, I started seeing the mosquitoes struggle. I thought this had to be a coincidence. I thought thermacell was just deterrent but I think it killed them. After they died I didn’t see a single hell beast all night long. I wanted to leave a review immediately and tell everyone their savior has arrived but I was still in denial that it was truly as effective as it seemed. Beginners luck? Second night: I turned it on and decided to put on shorts and a tee shirt, leave the doors all the way open, just closing the curtain and didn’t fog. I know that seems like I’m flirting with death but anything for science, ya know? Nothing!!! Not one fly, moth OR BLOOD SUCKING ABOMINATION!! It’s so small yet so powerful. I think I’m going to build it a shrine at this point. Bottom line: it’s easy to use. It’s not bothering my animals. The battery life is stable and stays on the full advertised 9 hours. It’s portable/small and you can place it anywhere. It’s silent, has no smell and releases a tiny bit of barely visible vapor. It’s just incredibly effective! Oh and I love that all parts are black including the device, dock, cord and charger block! Some companies get cheap and use white charging blocks for each color to save money. Cons: Espennnsiveeee!! Especially for daily use. Also, you can’t use it while it’s charging and charging takes hours. That’s about it. I already bought a second one to use while the other is charging. Edit: the fourth night I started seeing mosquitoes and thought it really was too good to be true but I checked the cartridge and saw my 36 hour refill cartridge (which should have lasted at least another 10-ish hours) was empty. I was unaware you HAVE TO PUT THE BLUE CAP BACK ON WHEN YOU’RE DONE! Especially when the device is charging because it gets warm and the juice will evaporate through the wick even when the device is off. It will evaporate super fast if it’s very hot outside so placing it in a cool place will help too.

It only does one thing and does it well
This repellent is very effective, better than any torches or waxes. I've placed one in my spring area and no longer get bothered. The thing I liked the most is the simplicity. Easy to add a cartridge and turn it on. Even my children know how to set it up when they go outside to play. Keeps the mosquitoes away! Also a big plus is how small it is, compared to the waxes I've had to store each season and the torches I have to buy and leave room for. Both the cartridges and battery lasts a long time. I would absolutely buy more and as gifts for friends as well.

Good but pricey
Overall I love the Patio Max. It is easy to get started with it and easy to charge. It hold a charge well. It also seems to keep the mosquitos away pretty well and that is saying a lot when you live in Georgia. We have mosquitos everywhere. We love to sit on the porch in the evening which is when the mosquitos are out the most. All you have to do is turn it on and wait about 15 minutes and then go out to a covered porch. It doesn’t have a strong smell like a lot of other products which I really like. The only thing I don’t like about is if you forget to turn it on for a while before you go out it doesn’t work quickly. You have to turn it on for a while before you go out to have good coverage. I would continue to buy though, and recommend to friends and family.

Easy to use I did not see a reduction of bugs
I am reviewing the Thermacell E Zone Guard Patio Max Mosquito Repellent. We have many bugs in South Carolina. Many bugs. I placed on the porch and on the picnic table by the water at the lake and at my house. It works okay, for the cost of the repellent I was not impressed with the performance.It does not work on gnats or flies. It is easy to use and if it kept the bugs away I would reconsider. The charging system is easy to use and it charged pretty quickly. I can visually see the vapor coming out and I do not recognize or smell anything like insect repellant. Maybe need a bigger machine to work in my area that is more powerful. For it to be rated to last for 12 hours I think it will be to costly to continue using.

Boom!!!
I was actually really impressed with the Thermacell Mosquito Repellent System. I’m one of those people mosquitoes seem to find immediately, so I’m always looking for something that works without having to spray myself from head to toe. This was super easy to set up and I love that there’s no strong citronella smell, smoke, or sticky bug spray involved. I can just turn it on while I’m sitting outside and basically forget about it. It makes being on the patio so much more enjoyable, especially in the evening when the mosquitoes usually come out in full force. I also like that it’s small enough that it doesn’t look obnoxious sitting outside. You do have to remember that the repellent refills eventually need to be replaced, but for me that’s a pretty fair trade-off for not getting eaten alive. Definitely something I’ll keep using during mosquito season. If mosquitoes love you as much as they love me, this is worth trying!

Works effectively
The best thing about this device is that it's portable. It comes with a rechargeable internal battery, so you can take it anywhere. We tried it in our backyard for a full evening and it was really effective. We got 3 days of use out of it before it needed recharging. It takes about 15-20 minutes before we noticed it being effective. However, at that point, it really works. Keeps mosquitos away in about 15 ft radius as long as it runs. There is only one button to manage it. It does come with a cartridge and even after using it for a few days, it still seems to have a lot of use left.

Gets the Job Done 💪🏻
I'm a smoker, so I sit outside with my roommate's adorable pup many times throughout the day. We live in a bit of a wooded area, so in the summer and fall, the rain foments an insurrection of mosquitoes breeding/hatching like Solomon and his 700 concubines. I happen to be one of those weirdos who attracts mosquitoes as if I were sweating gold. With the newly found cases of west Nile in my state, I tried to be smart about keeping these leeches off me, to no avail. I tried the burning coils, sprays, ands a different manufacturer's repeller/fan. I used those products for a couple of weeks and would still find myself with anywhere from 2-8 mosquito bites every time I went back into the house. Upon recommendation, I quickly placed an order for same day delivery for this product. As soon as my product showed up I charged it and went back to sit in the same two spaces I regularly lounge and experienced ZERO mosquito bites. I was out there for almost 2hrs. I highly recommend this product, especially because of the extremely affordable price. To date, I've spent close to double the cost (including MULTIPLE replacement cartridges) on the inferior product. No odor, quiet motor, HUGE protection zone, easy loading, and VERY effective. Only thing I might change is the length of time it takes to fully charge, but even that is a miniscule portion of this high quality product. 💪🏻

Good Thermacell Product
The Thermacell E-ZoneGuard is a pretty good but pretty standard Thermacell product. I've used 2 other Thermacell products in the past including their butane powered version and they all work about the same in regards to repelling bugs and mosquitos. I definitely prefer their battery versions over the their butane versions in the way they work as they are way more convenient but you have to have power so these battery versions are not great for camping if you won't have a way to charge it. I can't speak to how long the battery lasts on this one but the battery on my other lasts about as long as it says it should. We can usually get 2-3 nights of use out of one charge before needing a recharge. The nice part about this unit is it can be charged with a USB C connector or the charging puck that it comes with. The puck is nice you can leave it plugged in and just set the Thermacell on it when you are done to charge. The one thing I hate about the Thermacell design is its basically a wicking design so be sure to put the cap back on the refill canister when you are done otherwise it will dry out and you will use product over time when its just sitting around. The repellency of this product is hit or miss. It does vary a lot by area you are in and how bad the bugs and mosquitos are. It does repel some other bugs besides mosquitos but definitely targets mosquitos the best. However, if the mosquitos are really bad outside this thing doesn't seem to do much. We usually combine this with other methods of mosquito repellants like essential oils. This is typically how we get the best results from deterring mosquitos is using multiple methods. Like I said this thing helps but it is not a cure all for mosquito repellency

Bad charging, complicated returns, unhelpful seller.
This item uses an outdated charging cable and does not hold a charge well. When attempting to return the item, the seller refused to provide collection and instead sent lengthy and complicated return instructions, eventually leading to the return window expiring.

Me funcionó muy bien
Muy eficiente, lo use dos veces y ninguna picadura tuvimos, pero NO DURA mucho el cartucho que viene, solo duró como 12 hr

Wonderful mosquito repeller
We live nearby a lake and struggle with mosquitoes at home and camping and this has been a blessing to keep them at bay!

Refill arrived half full.
The product wasn't packaged properly. The refill unit had leaked into its plastic bag and absorbed into the cardboard box. Not only do I have less repellant, but metofluthrin is toxic and not supposed to be handled.

Excellent mosquito repellent
Product works like a charm. U like the Indian versions of repellent that are also effective, this one is odourless and vapouriser free. Only drawback is that there is no adequate supply of refills. Im struggling to procure one. Any leads will be much appreciated.
