Thermacell E-ZoneGuard Patio Rechargeable Mosquito Repellent, 5.5-Hr Bat | Black; 20-FT Zone; 12-Hr Refill; Scientifically Proven Outdoor Protection; Bug Spray Alternative; Scent Free; DEET-Free

I purchased the Thermacell E-ZoneGuard Patio Max Mosquito Repellent along with one box of refill cartridges 120 Hour. It came with one cartridge so that left me with a total of four cartridges. I works very well. Those four cartridges lasted me two weeks. I ran out of cartridges and I can’t stand to sit on my back patio right now. The mosquitoes don’t go away until mid morning and come back pretty early in the evening. With the Thermacell E-ZoneGuard Patio Max Mosquito Repellent I can sit out there just fine with no problem! The cartridges are very pricey but worth it if you like to sit outside as much as I do.

I recently purchased the Thermacell ZoneGuard Mosquito Repeller, and after using it on my lanai for a few nights now I never want to be without it. Living in Florida in the heat and humidity the mosquitos are boundless. It was very easy to set up and get working. Simply plugged in the cartridge refill and powered it on. Within about 10-15 minutes I noticed no mosquitoes were even coming near me. There was no noise from it at all - if not for the indicator light and its effectiveness / I wouldn’t even know it was on. I love that I can bring it out front while I’m weeding and it’s equally effective. Goodbye smelly tiki torches and messy sprays. I would definitely recommend this little gem!!!

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.

Works great! The mosquitoes were eating us alive on our back patio until we started using this repellent. I like that it is rechargeable and has a light. Refill cartridges are expensive but it’s better than getting bitten.

I've had it for a couple of weeks on a screen porch where a few mosquitos always seemed to sneak in to ruin the evening. It has worked to keep them out along with the ceiling fan. A couple of issues for me that seem to be a let down. The battery take forever to charge (hours) and no way lasts 5 hours. I only use it for an hour or so most evenings and had to charge in many times over two weeks of use. The second issue is that the repellent goes really fast, seems to not last as long as listed (12 hours). For me, it's really too hot to stay outside for very long, but perhaps I'm spending longer than I think since I'm not getting bitten. One tip I did get from their support was to bring it into the AC when not using it so it lasts longer and does not evaporate from outside temps.

At a certain point during the summer my yard because unusable due to mosquitoes. I have a mosquito allergy so the bites are painful, swollen and itchy for me. We have tried spraying the yard with a pest control company and that didn’t do much. I’ve seen this product and have wanted to try it for a while. This thing is a game changer. I can now sit on my deck mosquito free. I wasn’t sure it was working, and then one night walked into my yard away from it and got attacked by mosquitoes. Such a great product and so happy to have finally found something that allows me to sit outside and enjoy my yard again! I have had it for almost 3 weeks and use it for about 2 hours a day and haven’t had to recharge it yet. So battery life is awesome. It’s also rechargeable which I love since I’m terrible at remembering to buy batteries.

I like this product, my wife hates mosquitos and this thing creates like an invisible fence for them. It does take some time to start wokrging as the abrrier needs time to work, I say like 5 to 10 minutes then its good to go. Strong winds does blow away the barrier. The refills are a bit expensive but might be worth it as this does keep the mosquitos away. Easy to use, just charge it and pop in the repellent.

Imagine sitting on your front porch, a wonderful, cool evening. Five minutes into it, all you can think about is the annoying little buzz of a mosquito because he just won't quit. Now imagine running into a phone booth, putting on an invisible superhero costume, and running back outside to swat all those mosquitos away. But wait! You don't have to. This Thermacell E-ZoneGuard Patio 5.5 HR makes it effortless to enjoy your evening without those pesky buggers buzzing around your body. All you really have to do is make sure it's charged up before your night outside, turn it on, and go back inside to make those cocktails. Then, after about 15 minutes, head out and your "zone" will be mosquito free. Nothing to apply to your skin. No annoying bug zapper noises!

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

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

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
