I’ve tried every type of mosquito repellent from citronella plants to mosquito sticks you burn and many electronic devices, BUT after my neighbors told me about this product and how well it works, I gave it a try. THIS IS THE FIRST TIME I CAN DIT ON MY PATIO AND NOT GET ONE SINGLE BITE. The mosquitoes fly close by, yet they leave me alone. Yes, the refills are expensive and you have to strategically coordinate the battery charge times so you have one charged at all times when you plan on being outside. AND, I spend ALOT of time on my patio (in Texas where the mosquitoes flourish). bought two units and swap them out as needed. If you can afford them, I highly recommend!!

This device is an absolute must-have if you enjoy spending time outside without being eaten alive! I live in Northern California and use it every evening on my back deck—and let me tell you, the mosquitoes don’t stand a chance when this thing is on. It creates a powerful invisible barrier that actually works. The upgraded light-up version is a total vibe—perfect for setting the mood at night and will be a huge plus when we take it camping. Not only is it functional, but it also adds a nice ambiance to any outdoor setup. If you’re tired of swatting bugs or getting covered in sticky sprays, do yourself a favor and grab one of these. I can’t recommend it enough!

Update (5/12/22): I tried using the product on a breezy evening and as I suspected, the wind impacted the effectiveness. While I think there were fewer mosquitoes (just a guess), I was getting bitten and decided to go back inside. I do think it’s effective if it is not too windy. Will buy some more repellent and continue using it. (Original Post). Let's start with the most important question...does it work? It does work (or at least has worked for me and my specific set up)...more about that shortly. And I will continue to use it (and purchase more repellant refills). Why only 4 stars? Instructions need to be improved and not quite sure about the value proposition (cost) for the repellents. But the product has worked for me so far (several hours of use) and I really hate mosquitos. And I did not have to put on bug repellent to keep them from pestering me. After reading several reviews and wanting to gain access to my patio without being attacked by mosquitos, I decided to buy this and give it a try. I decided on the battery operated version for my patio. The setup instructions were not clearly written (I will provide the information I wish they had provided shortly as well). I am not a entomologist or an aerosol vapor flow expert...that said, here are my observations and recommendations. 1.) I don't believe the graphic that shows a 20" protective bubble is reasonable representation of what to expect from the product. The unit emits a vaporized repellent into the air (visualize the smoke from a candle) which is highly influenced by wind or, a ceiling fan. As the repellent is diluted to into the air, the effect dissipates, meaning less protection from mosquitos. The graphic shows a group of people sitting outdoors with a bubble shield, exactly 20 feet around them. If there is no wind, maybe that depiction is a somewhat reasonable representation. But when you set an expectation that there is a protective bubble, people will take it literally. Hence the 1 star reviews that says it does not work. In my situation, I am on covered porch where there is a wall behind me and to the left of me but the front and right side are completely open to the wind. So there is a "pocket" where the repellent is protected from from being completely dissipated or blown downwind. This would seem to me to be the ideal set up for this device. Haven't tried turning on the ceiling fan on the porch. If the results are significantly different, I will update this review. 2. Confusing instructions included in the box at best. Here is a suggestion...how about a QR code that takes you to a video called first use. Let me summarize the information I believe needs to clearly provided: a) Plug the unit in before use (instructions said this). You will see 3 chasing dots (blinking on and off in a chasing pattern) until the unit is charged (instructions have some confusing series of gray and white dots that does not look anything like what the unit looks like while it's charging). When fully charged, the three dots above the charging port will be on. Also, no word on whether you can plug the unit into a wall socket and use it while it is recharging. And the instructions do not say it takes 5 hours to charge when the battery is completely depleted (that is what the support person told me). Also guessing the unit does not trickle charge when charging is complete...so you probably should not leave it plugged in for extended periods of time. b) The repellent is in a small plastic container with a lid. The instructions in the box don't really show you how to hold the lid to remove it (there is a confusing drawing with two diagonal arrows which wasn't useful at all). Hold the sides of the bottle with your thumb and forefinger. Hold the front and back center of the lid in the center with the thumb and forefinger of your other hand. Separate. Just like the picture on the Amazon website (which I just saw). c) How about a recommendation on turning it off after your use and whether to remove the repellent container and put the lid back on. Absolutely nothing said in the instructions. Also, maybe recommend charging the unit so it will be ready for your next use? What if you are not going to use it for a week or a month...should you not leave the unit plugged in to a charger for extended periods? Again, it would be useful to know if you can use the unit while it's plugged in and recharging. 3. General thoughts about toxicity: Google mosquito deaths and the results say mosquitos kill over 1 million people a year. One of the prominently displayed 1 star reviews talks about the toxicity and that you can get headaches or dizziness. Everyone is different and I enjoy being outside without having to put insecticide on my skin. I have not gotten headaches or dizzy. Your results may vary. Now I want to compliment Thermacell on their customer support. They answered the call pretty quickly, were very helpful and pleasant to work with. Also, very generous warranty. I have written this whole review sitting on my porch and did not have a single mosquito come near me. Houston, Texas, in May on light breeze afternoon. Again, I would recommend it to friends and would buy it again. Now for some unsolicited advice to Thermacell. Seems to me you have way too many versions of this product which confuses the buyer. Also, it appears the repellents have changed over time with some of your later repellents that are "safer" than your earlier versions. Might be useful to make this information more explicit if correct. Hopefully you are reconciling what products to sell and which products to sunset. Also, on the box that is covered with pictures and graphics, the actual product version was in smaller print and greyed out (easily overlooked). So it took me a minute to find it when support asked me what device I was calling about. Very simple electronics upgrade...I would recommend resettable timers on the device indicating battery life and how much time remains before the repellent needs to be replaced. Either LED timer display (not 3 LED lights) on the device or bluetooth app on your phone. Seems obvious you are using the "razor and blade" method of pricing for product, where razors are cheap but the blades (refills) are where you generate your profits. The unit works well enough that a little upgrade to provide the user more information about battery life or how long until I need to replace the repellent cartridge would justify paying extra for the "razor". Just one opinion and you have been in the business for 20 years...so you know what your are doing.

We live in south Texas where the humidity and mosquitoes make it difficult to enjoy sitting outside. We’ve tried citronella lamps, mosquito repellent sprays and lotions, bracelets with essential oils, etc., but nothing kept the mosquitoes away. We had resorted to just turning on fans to have constant air moving to disturb their flight, but they still found a way. I’m a mosquito magnet. This little contraption WORKS! Just turn it on 5-10 mins before going out and enjoy hours of mosquito free summer nights! We’ve sat outside for weeks now and NO bites!! It’s great and doesn’t give off any funky odors. No more lotions or sprays!

This little power house keeps bugs away even when professional spraying does not! We literally cannot enjoy outside without one of these. Easy to use, fast to act. Did have to replace after a year. Can’t live without. Little worried that it is so powerful that I don’t let kids sit by it…can’t smell anything, but there must be something strong in this 🤣. Thank you for giving us our yard back during the summer!! 🎉

So far we've only used this one evening, but I'm pretty sure that I'm a huge fan. Mosquitos were swarming us until I brought this little gem outside. Not one mosquito was in sight after that. Highly recommend!

Item just arrived but it did not have any packaging. It was obviously a used/returned item sent in a generic box taped together. The thermacell device itself looks a little rough arounf the edges. The description did not indicate this was used or refurbished so I'm surprised by the poor shape it's in. Beware when buying because you might get a used one. I will probably return for a different brand.

As a stand alone product..... It's just okay. But as an additional layer of protection.... It's great for that. Wind can affect how this works, as well as where you place it can also be a factor, and it doesn't repel all insects....mainly JUST mosquitoes. So, as a stand alone product.... It's alright and definitely better than nothing. But this to me, this is more of an additional layer of protection than sole protection lol

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

Nice compact design and keeping us free of bugs

I like the product and found it to be effective against mosquitoes. The problem is that it is not possible to buy refills and is therefore a complete waste of money.

The unit itself is great but the refills don’t last very long and it seems are imported from America. Cost of refills for the rechargeable refill is way more than the gas refills for standard original thermacell mosquito repellent .. hence 3 stars than 5 but effectiveness is 5 star
