Thermacell E-ZoneGuard Patio Rechargeable Mosquito Repeller with 20-Foot Zone of Scientifically Proven Outdoor Protection; 5.5-Hr Battery; 12-Hr Refill; Bug Spray Alternative; DEET-Free; Black

My god, this stuff really works! BIG TIP...turn it on 15 minutes before you plan on occupying the zone. We live in Texas about 50 yards from a wet weather creek, and it's been wet for months. We also have gutters that stay wet and constantly breed mosquitos. I have to wear long sleeve shirts, pants and boots to garden, or the mosquitos will carry me off. This little machine is completely quiet and emits no odor at all. My husband and I both agree it's just weird to be able to sit on the back patio and not have to fight the mosquitos. We love it! If there is a light breeze, be sure to sit downwind. I don't know if you will benefit from this machine if it's moderately windy. I don't think the mosquitos can land on you very well if it's windy. I like how long the repellent lasts, and the battery lasts a decent amount of time also. It's easy to recharge. I like the lights and beeps that let you know when you've turned it on and off. I came back to get more repellent BEFORE I run out. What a blessing!

I was skeptical of mosquito devices, but this E-Series repeller is amazing. It has a sleek, modern design and creates a 20-foot barrier of protection that keeps all the pesky bugs away. No spray on the skin, no smoke, and no noises. It is most effective when it's calm or there's only a light breeze. If there are windy conditions, the repellent bubble tends to drift and not stay in your space.

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.

This item is my new outdoor friend. Since it is small, portable and rechargeable, I am able to move this to any area I am hanging out. I use our Thermacell E-ZoneGuard Patio repellant to keep mosquitoes from ruining family outdoor time—whether I’m eating outside, hosting friends, camping, or relaxing on the patio. It creates a solid 20-foot protection zone around me using a smoke-free, scent-free formula that targets mosquito sensors to drive them away, without needing bug sprays or lotions on my skin. The protection stays consistent over time and is scientifically proven to repel mosquitoes. It took less than one hour to fully charge and the machine last just over 5 hours on my first use. It takes maybe 15 minutes to fully warm up before it becomes fully effective. Great Features: It runs on a rechargeable battery for up to 5.5 hours, is TSA compliant for carry-on travel (next tropical vacation?), and the starter pack includes 12 hours of DEET-free repellent refill. It’s also people and pet friendly, independently tested, and EPA reviewed—making it easy to use and safe. Charging is simple with the Micro-USB connector (included).

It definitely works, even for people prone to being constantly harassed by mosquitoes on my porch, within a couple minutes of turning the unit on, the bugs are gone. But it’s also expensive, and the refills run out quickly. So the question is: are you willing to shell out a lot of money for a mosquito repellent, no matter how well it works? If you are, this works.

Absolutely love this Thermacell. As a mom with kids always running around outside, I needed something that actually worked without spraying everyone down with bug spray every five minutes. This has honestly been a game changer for backyard evenings, sports practice, and sitting outside while the kids play. It is super easy to use, quiet, and I love that there is no strong smell. After letting it warm up for a few minutes, we noticed way less mosquitoes around us. The rechargeable feature is also really convenient and cute because I do not have to keep buying batteries. Definitely worth it if you have kids and want a more comfortable outdoor setup without constantly fighting mosquitoes.

This unit has a problematic charging port; takes very long to charge; charge doesn't last as long as other models. I do not recommend this model. I have 2 thermacell units that sit on a recharging base. That's what I meant to buy. My mistake for not noticing the model in photo was different. Kept it thinking it would be fine. It's not.

Tried this on a couple warm nights and it works well at repelling mosquitoes. It is a nice compact size that covers a large area. There was no odor or difficulty breathing when it was on. My family and I loved not having to spray bug spray on our skin. I love that this is rechargeable and it charges fairly quickly. The downside is it doesn't work well if the wind is blowing and the repellent refills are pretty expensive.

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.

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

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.

Buena barra protectora para que no se acerquen los mosquitos pero si hace mucho aire no está al 100 de protección También le di 4 porque los repuestos son algo caros

En esta época es muy molesto estar en la tarde y noche en la terraza. Los moscos de verdad me hacían correr a meterme a la casa. Lo probamos el fin de semana y la diferencia fue notable. Vimos de vez en cuando algún mosco (no hace magia), pero NADA que ver con la cantidad que había antes. No son baratos los repuestos y veré la opción de pedirlos a EUA, pero para mí valen la pena.
