E90

Bought this ahead of Memorial Day weekend with the kids' summer game schedule in mind. The weekend was the first real test and it earned its place in the rotation. We were outside for extended stretches and the Thermacell did what it advertises. No noticeable mosquito pressure in the zone it covers - which, for where we live this time of year, is meaningful. WHAT WORKS - It just works. Turn it on, give it a few minutes, the area becomes mosquito-quiet. No smoke, no citronella smell, no open flame to keep an eye on with kids running around. - Rechargeable is the right design choice. Not having to find batteries or fuel canisters every time you want to use it makes it actually usable, not aspirational. - Quiet. You forget it is running. - The portability is the part I am most excited about. Kids' football, baseball, and outdoor practices are exactly where I want this on the sidelines. No flame, no spray, just set it next to the chair and forget about it. WHAT DOES NOT - One weekend is not enough time to fully grade it. Memorial Day was the test. I will know more after a full summer of game-day use, and I will update this review if anything changes - durability of the unit, refill costs, whether the 20-foot zone holds up as advertised across longer sessions. - The 20-foot zone is a defined area, not a backyard-wide solution. If you have a large open space and people spread across it, you will want more than one. For a patio, a tailgate area, or a sideline chair cluster, the size is right. WHO IT IS FOR Anyone with kids in summer outdoor sports, anyone who hosts on a patio in mosquito country, anyone who has been using citronella candles or spraying everyone down before they sit outside. If you need full-yard protection, you will need more than one unit - this is built for a defined zone where the people are sitting or standing. Five stars based on one weekend of use. Will come back and update after a full summer of game-day testing.

⭐⭐⭐⭐⭐ I bought this specifically for camping and drive-in movie nights, and it worked perfectly! It kept mosquitoes away without any strong odors or sticky bug spray, so we could actually enjoy the nature. It’s compact, easy to set up, and lasted the entire evening. I’ll definitely be bringing it to every outdoor movie and camping trip from now on.

We live in an area where there aren't a ton of mosquitoes, but the ones we do have are persistent little fellows. They are also the fastest and most agile bloodsuckers I have ever encountered. It is like they have a detection device because as soon as you look at them, they take off. They are huge fans of ankles. Anyway, we bought one of these to try to make our morning coffee and evening cocktails a little less like a visit to the Red Cross Blood Drive. We bought one and the results were sporadic. It seemed to reduce the number and also slow others down enough that you were able to swat them. But it certainly didn't eliminate them. We got a second one and now we put one down by our feet and the other on the table. This has seemed to do the trick (so far). Will follow up as we get more use. They are easy to use, silent, and odor free. As others have stated, they DO NOT work well with even the slightest breeze. And, despite Thermacells claims, it does not have to be a strong enough breeze that it keeps the flying phlebotomists at bay. My only other complaint is how long it takes to recharge. The battery life is not great, and it takes FOREVER to recharge. I really wish you could put rechargeable AA's in it instead. All in all, decent but not great.

I purchased the E90 Rechargeable unit that claims a 9 hour battery life, and included a 12 hour repellent refill cartridge. It was delivered the day after I ordered it. Very quick! This cute little critter killer was easy to setup even though the instructions were NOT very clear, however, after waiting a ridiculously long time (over 4 hours) for it to charge enough to actually use, I was only able to use it for a couple of hours last night and less than one hour this morning. The "refill" cartridge included in the package was LESS than half full of repellent liquid (this can't be normal?) right out of the box. Once it had warmed up and started effusing the "mist", I only used it for a couple of hours, then went to bed. During the time it was in use, I did not get bitten by any mosquitos, but I have no idea if the little critters had simply stopped being active or if the repellent was actually working. Assumed I'd be able to get a better indication of its effectiveness the following morning. Well, it's now the following morning. After powering up the unit and waiting for it to begin effusing the mist, the mist lasted only about 20-30 minutes. So, I removed the top of the unit and looked at the cartridge which was completely EMPTY! This was supposed to be a 12 hour refill!! I got less than two and a half hours out of it. The battery charge indicator says its fully charged. This Thermacell E90 Mosquito Repeller might truly be effective in keeping the critters away, but I think the company owes me a free refill cartridge that is completely full and will actually last the full 12 hours claimed on the box and in their description. Very disappointed by this experience. THERMACELL??

My backyard is full of mosquitoes and I hate the smell/feeling of bug spray. I sat this outside and I never got bit once. This is the first bug repellent I have ever bought that has worked 100% AND it has no scent which I love. I have charged my device once and used it multiple times without having to recharge.

Took this to the islands with me during vacation and it worked great!! I used it in the bedroom every night. There is no smell or ordor. The cartridge it comes with is small and only lasted one night so we bought larger replacement cartridges to last us the rest of the week. Overall, this is a great way to keep mosquitos at bay and sleep soundly. Though, over time, can get expensive with the cartridge replacements.

Effective occasionally. It's not totally effective if there is any wind or air movement (breeze or fan). If it runs long enough it is somewhat and it's relatively calm. The cartridges are expensive and last no where near their advertised longevity.

Thermacell is one of the top rated mosquito protections for your patio and camp site. The 20' protection zone applies only if there is no breeze from the wind or a fan, so I find I have to use twice as many as expected in real-world conditions.

Honestly useless I put it for an hour. I sit next to it and I got 100 bites not worth it
