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 tried the Thermacell Mosquito Repellent, and I must say I was surprised at how well it works. It is easy to assemble and use. It didn't make a mess like other on skin repellents and it had little to no smell. I didn't get bitten in the 20ft of space advertised, but as soon as I moved away from this "safe zone" I could feel the mosquitos on my legs!

I bought this product two weeks ago to use for after tennis match social time. We play outside and the mosquitos are typically out in droves around dusk. The unit kept away the mosquitos and the little gnats that like to annoy us. We were able to gather around the picnic table and socialize without being bothered and bitten.

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.

I recently had an opportunity to put this product to a serious test, and I'm impressed. I'd charged my Thermacell in preparation for some upcoming yardwork. The weather had other plans however. We were hit in this area by some serious storms today including a few tornadoes that knocked out power for hours. Nearly 12 hours without power in muggy, warm weather kept us wanting to have the doors and windows open once the rain passes, but we were getting hit pretty hard with mosquitoes until I remembered I'd already charged the Thermacell and had a cartridge ready to go. I placed it outside our door on the porch, and it kept us pretty much big free for the remainder of our time without power. I'm so thankful we had this on hand. It's effective, easy to set up and use, and a great little gadget to have on hand. Cannot recommend enough!

This little guy is our new must have summer accessory. It truly keeps all bugs away while outdoors. If you live in the south you understand! It last quite a while, is rechargeable and the cartridges are low price for what you get in return. Def go buy one or 2 for al your outdoor adventures.

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

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.

We have not been able to use this at all since we purchased it. We have charged it, reset it, put in new cartridge and nothing. The lights come on and circle for about 2 minutes and then go completely out. When we try to turn on, a red light comes on and then goes off. I was thinking about purchasing another one, but don’t want to waste any more money.

I bought the thermacell without telling my husband because he wouldn’t believe it works. Sure enough, the moment the package arrived he started with his negative comments. As the sun began to set I turned it on and for the first time we stayed outside until almost midnight without turning on candles, a fire, or spraying ourselves. Not one mosquito bite. Now we take it with us whenever we’re invited to a cookout and people laugh at us until they start getting bitten and we’re sitting comfortably next to our thermacell. For that reason I’m buying another one and ditching the tiki torches and candles. It works. It works great. It allows us to use our back yard without smelling like a fire pit or bug spray.
