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.

I was skeptical, but my backyard swarms with Mosquitos and this keeps them away and not a single bite. As soon as we turned it off, they were back and we were fighting them off by hand. I'm a believer and don't sit outside without it. Thermacell gave us our deck and yard back.

I got my E55 unit a few weeks ago and brought it with me whenever I went fishing. It is lightweight and portable, and the battery lasts a good amount of time. In my experience, it repelled some mosquitoes, but a lot still kept attacking me even after 30 minutes with the unit being on by me. It also still uses micro usb and not usb c.

This product does work, put it outside and it went to work. Yes a few mosquitos got me but what product out there is 100% foolproof without having to larger yourself in chemicals every few minutes. The battery life could use some work but other than that it worked wonders.

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.

This machine is the best! I live in Florida and we have mosquitoes here most of the year. Since I’ve set up the Thermacell I have not been bitten once! It takes about 20 minutes to warm up and protect your desired area but once it’s up and running you are good to go. Thank you Thermacell!

I have not been able to enjoy my porch and yard during summers. I just learned about Thermacell products and used my new E55 for the first time today. In 15 minutes the swarm of mosquitos disappeared. I stayed out over an hour without a single bite. It is like magic! It works exactly as you describe it! After use I capped the 12 hour cartridge and have enough left for a few more times on my porch, but before it runs out I’ll have one or more 40 hour refills. No mess, no smell, and when I came back inside there were no mosquitos by the door to enter my house! I wish I had know about this device before! And it is well made - well designed.

We used this for 4th of july to watch the fireworks at a park. Around this time of the year the mosquitoes here are every where and my youngest always gets a few bites. This time she did not get any mosquito bites. I definitely recommend using this device.

We used this on both our back porch in Chicago and up north in Wisconsin and it definitely kept the mosquitos away. It was convenient to bring with us. The charge is easy and the install of cartilage is simply. I like at night, when you shine a light you can just see a long of bugs but this little things keeps them at a distance. I look forward to bringing it camping with us in a couple weekends.

Works well for the most part, perfect weather works very well with no problems, weather seems to affect the effectiveness of it, but that might be expected. Battery seems to last as long as I've needed it to.Refill doesn't seem to last as long as it claims unless you use it 12hr straight? Seems to take longer to recharge it.Overall it keeps the bugs away, no smell or spays
