So far using the Thermacell E55 in the backyard helps keeping mosquitos away. It is effective and better than sprays. It is portable, lightweight and easy to use. Strongly recommended for family outdoor activities like camping or just relaxing with friends in the backyard.

Our back patio design incorporates a small pond that is white smoothing but attracts mosquitoes. The small Thermacell E55 unit keeps the critters at bay. I like it's rechargeable and more importantly the battery charge lasts for multiple days and uses. The 12 hour refill does last about 12 hours. Excellent product. It makes our patio area go from good to great. No more mosquitoes

I went on a camping trip in Yosemite National Park this past summer to test this product out. I tested this repellent and it worked better than I had expected. I turned it on and within 15minutes the mosquitoes and flying insects were only hovering on top of me instead of biting me. The unit itself is not too expensive but the refills are a bit pricey. The refills will give you 36hrs of protection against mosquitoes so to me I think it’s worth the price.

This little repellant worked like a charm. We ate outside up in the woods of Wisconsin. Not only did no one in our group get a bug bite, they didn't even know I was using the little repellant. Definately a must use for any outdoor activities where the bugs are wild!

I've read the one star reviews and frankly, I don't get it. These repellers are the real deal. Silent. Effective. No scent. User friendly. I have used these units for three weeks and not seen a mosquito. Yes, they are slow to charge and recharge. That's why I purchased back-up units. In my opinion, well worth the cost.

Took the family on a camping trip and the mosquitos were absolutely horrible! If it wasn't for the Thermacell we would've just packed up and left. After about 20 minutes we noticed no one was being bit up. Bug spray and citronella didn't help anywhere close to the Thermacell. I highly recommend!!

Received this product for free if I have my honest opinion. Now I haven't gotten a full opportunity to use it outside. I used inside my house because we were having bug problems on top of some mosquitoes getting inside. And it worked wonderful I would even forget that it was on and we would leave it on through the night. I'm in need of a refill from using just inside the house but there was a MAJOR DIFFERENCE of the amount of bugs I was battling with in my house. But will definitely putting that to the test this weekend as we are going to be outdoors a lot. I cannot wait to see what it can do outside.

What a great solution to mosquito problems. I have 4 kids so using mosquito spray is a big much for us. You spray it and then everyone is coated in it - and it's all you can smell (and sometimes taste!) My family and I love the compact repeller and the fact that it's rechargeable makes it so was to use. It covers a large space (UP to 20 ft) My next step is to see if I can use it on a hike. Feeling optimistic

I have used the product and it works well. However the refill does not last 12 hours as advertised. It was empty in less than 6 hours of use. I have purchased a 40 hour refill and I hope it week last 40 hours as advertised. The refills are very expensive. This is a low cost product but it works.

I live next door to a pond with lots of trees and bushes around. I love to hang on the back deck throughout the day, but the mosquitos are quite bothersome because of the terrain and foliage. During the summer, I can see them waiting for me outside before I even step through the doorway! Not to mention, the mosquitos we've had are the new varieties - 'Aedes aegypti' and 'Aedes albopictus' which bite throughout the day...so we never get a break from them. At our wits end, we finally broke down and bought the Thermacell rechargable. I couldn't be more pleased! I can finally enjoy my beautiful deck! It works well for us. I've tested it extensively and while I do see an occasional mosquito, it continues flying by without landing on anyone. It always works. When I don't use it, I can tell quickly as mosquitos begin to swarm again. Is it expensive? Yes, absolutely. The price is quite high for the refills and that is the downside to this great product. The refills are quite costly if you have to use this product on a daily basis. But the payoff is the peace of mind that I can sit outside and drink my morning coffee or make Smores in the evening with the kiddos without worrying about West Nile or yellow fever, or at the very least, the welts that don't go away for days. This product is worth it!
