ThermacellRechargeable Mosquito Repeller Refills; Advanced Repellent Formula Provides 20 Foot Protection Zone; Compatible with Thermacell E-Series & Radius Only; No DEET, Spray or Flame

The Thermocell changed our outdoor experience. As long as we have plenty of the Thermocell refills I don't have to worry about my grandchildren, my family being eaten alive by pesky mosquitoes. These refills last for hours. I highly recommend it and will continue to buy it. You can place the thermacell anywhere and it's guaranteed to work. Since we've had these we no longer get bitten by mosquitoes.

Works. Cannot attest to a 20 square foot radius, but it does work great when close by. I got about 25 hours out of a cartridge, but another reviewer claims that if you put the little blue cap back on when it's not in use, it lasts longer, so I started doing that. Mosquitoes hate this stuff, I was getting swarmed until I turned it on and they *poof* all of a sudden disappeared. Needs to be charged up every 10 hours or so, good little gadget.

Effective way to protect yourself from mosquitos when gardening. These Refills last quite a bit longer than the ones that come with the original unit. My backyard is a wetland & it's a challenge to escape being biten to death. This product allows me to garden without getting bites. Amazing product.

I originally purchased the thermosell rechargeable based off of a co workers recommendation. They seem to work well after being on for 10-15 minutes when I'm out in the barn at night farting around. Good enough that I bought a second one.The refills are a bit pricey but last longer than the one that comes with the device. This is my second purchase of refills.

I have always reacted strongly to bug bites. Mosquitos and other bitey bugs love me, and I get big reactions to their bites. Not a great combination, especially for someone who lives in a very buggy area in the Desert Southwest.I've tried lots of various bug deterrents, but Thermacell is the first one that has actually made a huge difference in my outdoor experiences.It takes a few minutes to warm up and create a barrier, so usually my husband takes it out and sets it up before we plan to go out. There is a detectable scent - I don't find it either pleasant or unpleasant, but it's there.But this thing works.Before we started using Thermacell, my daughter and I were getting dozens of bites, and were absolutely miserable. After we started using Thermacell, the bites went to near-zero.The refills are very easy to use, and they last an acceptable period of time. If we forget and leave one out overnight, we'll have to replace the refill, but if we use it only when we are outside, it lasts a while.

We plug the Thermocell unit in on our patio and it has worked flawlessly. No mosquitos for about 20 feet.
