[This review was collected as part of a promotion.] works great

Ran the Radius for about 90 minutes and about half of the liquid in the refill was gone. Seems like it should last longer. OTOH we had no mosquitoes.

I have no idea how these work, but they're amazing. We live 100 yards from a pond, and the whole yard is filled with mosquitos. But our patio is completely clear.

I love these and the machine. Well worth the money. But not sure it last 40 hrs. My 12 hr or 18 hr that came with my machine out lasted 2 other 40 hrs.

I've been using the Thermacell radius for two years now and I love it! I recommend it to friends constantly. Perfect for keeping me comfortable on my patio.

My daughter (a mosquito magnet) cannot visit me for outdoor meals unless the mosquitoes are under control. The Radius is the first device that has made this possible.

I use my Thermacell to keep the mosquitoes at bay on my back porch. It works like a charm and I would absolutely recommend it to anyone who has a problem with these blood sucking little critters!

These really work this summer on several occasions I met other people that were using the thermacell device that were finding the Thermacell device was really keeping mosquitoes away.

Really helps when we are out on our patio. Works best when its on the ground between us (on a table seems to leave and area "untreated" and we get some mosquitos)

It's ok. Cartridges leak so there is definitely no chance of getting your moneys worth. Coverage zone is much smaller than advertised. Maybe the other stuff they sell works better, I don't know.
