Device is too expensive, refills are too expensive, there is still an amount at the bottom of the cartridge that is unusable and it only works so so at keeping mosquitoes away. Other flying insects like gnats, etc. are not affected by it at all. Definitely not worth what I paid and I certainly would not recommend it to anyone.

I mean the thing to rate is the machine not the refills but they asked me so here goes. I hate mosquitoes. I find them to be annoying and painful and I would do almost anything to be rid of them. So of course I buy the biggest refill size. Yes it’s a flex and I will brag about it whenever I see my fiends and family in person again. I’ll tell them how this stuff is an investment. It’s golden

Unfortunately I don’t know if the mosquitoes in my area are just TOO much for this machine, or if the machine is just not what it markets itself as….But there are ZERO changes in how often I swat around my body when I’m outside. I was really hopeful this would work, but I don’t think it does.

I have every kind of mosquito repellent you can think of for my apartment balcony…cintronella candles, OFF, the tennis-racquet-looking zapper and I use all at various times. Same with this. I will say it’s most effective after it’s on for awhile. It doesn’t get them all (hello zapper!) but it works very well for the most part. A little breeze won’t affect it but a windy day will. I feel if the opening were bigger it would dispense and work better but then how quickly would you go through the cartridge? That would get expensive. I also wish the battery would last longer. I am happy with the product and would recommend.

I have been using the Thermacell Portable Mosquito Repellers for years now, have two. So I got a Radius to try. Works ok a little annoyed went camping and the power dies. the long lasting refills are NOT the total hours they say they are, about three to four hours short on juice. Its now sitting back in its box and the handhelds are in use.

We've used this for outdoor dining for a few weeks now and it seems to work well: no mosquitoes at the table; no obvious odors; nice form factor -- easy to charge and use. Good product! It remains to be seen how long the 40-hour refill lasts but it's clearly enough that we can use the device all evening without worrying about running out and needing to re-order. I purchased 3 of the 40 hour refills and expect to make it through the remainder of the summer and hopefully into next season. FWIW I spray Raid "Yard Guard" around the table about 10 minutes before we eat and start the Thermacell then, keeping it under the table (our legs are usually the most exposed). This regimen is working.

I waited to review this products until after I have been able to use it a number of times in different situations, time periods, time of day and during different activities. Thermocells are amazing. I use to hate cooking/eating outside later in the evening during the summer due to the amount of biting bugs that would invade our backyard while we ate. I bought two units and have not had one complaint about mosquitoes or gnats from my family. Amazing product.

Used this product previously and like the quality
