!!!

I’ve recommended these to everyone of my friends and family who complain about mosquitoes. It’s a miracle device! Mosquitoes just gone vaporized poof into the nether realm within five minutes, turning it on haha. Yes the refills are a bit pricey, but use it sparingly and remember to shut it off when you’re done!!!! They should last quite a while as long as you’re not sitting outside all day long. IDK what their proprietary secret sauce cost to produce for the refill so IDK if they are overcharging, they may just be recouping manufacturing cost! Either way two thumbs up!!! :) also I got the main unit on clearance and it was about half the cost of a refill pack score!!!!! Haha

Works fantastic on mosquitos and sandflies

I've used our thermacell products (we have both types) in areas with tons of mosquitos (north Idaho) and outdoors in the summer. You can literally see a wall of mosquitos just at the edges of coverage but within - nothing. We even took it to the south island of New Zealand to help with the sandflies. It was amazing. Highly recommend these products.

Essential from the backwoods to the backyard

Nothing beats my Thermacell when the mosquitoes start coming out. They vanish in minutes and don’t return until I turn the device off. It is so easy and practical. I keep my refill stash full for the season! Great technology for use in camping and hanging out in the backyard, the park or anywhere there are mosquitoes.

I was skeptical but wow it works!

First off I almost never give reviews so the fact that I am writing, says this is great enough that I’m making the effort. Secondly I’m the type who believes zero advertising claims but am willing to give things a shot when, like w/this, independent reviewers (NYT Wirecutter iirc) give a thumbs up. And wow, I put this baby on the table on the patio and got zero bites—I’m a mosquito magnet but we didn’t even see a bug all evening. I’m a convert!

Effective

Noticeable reduction in # of mosquitoes, especially if you allow it to run for about 15 minutes before you need it. It won't eliminate 100% of the buggers, but it's a big help.

Refills

It worked great hoping my refills will be okay in my RV as I use this product only when we travel in our RV I have no problem with mosquitoes where we live.

Thermacell products are for outdoor use only and the refills last several years in its original packaging.

Not for public reading, solve problem internally

I have arthritis thus unscrewing the turquoise knob impossible on some of the devices. The product itself is great, design needs help

Extremely expensive but safe

Can't really go higher than three stars because it's so darn expensive. Can’t really go higher than three stars because it’s so darn expensive. However, very safe. And company was letting the customer away the cost of their poor design, the way the cap comes off, resulting in some broken stems, which now they have remedied with a screw top cap.

Effective if follow guidelines. Love it/hate price. Hoping for knockoffs!

Not working Unfortunately

We have the small body units (2) and the larger unit for the patio. Doesnt seem to dissuade them from eating us. We have just ordered another type unit that is suppose to attract and kill them. It is so sad to be unable to enjoy the outside when it is beautiful out there!
