Won this in a raffle! Made my picnic bike ride with my 3 year old just perfect! Thank you Thermacell!

Now a believer
Bought it for a camping trip to Idaho. Some nights the bugs were terrible and I have to have the back hatch of my vehicle open to use my cooking setup. This repeller kept the bugs away and out of my vehicle, even with the interior lights on! Awesome product, I'm a believer now and will continue to use.

Amazing Product
A year ago we purchased our first MR150 Portable Mosquito Repeller after a friend recommended it. It works extremely well. This year we went to a provincial park that is know for mosquitoes. So we purchased a MR450. This is probebly the best one yet!!!! Zero mosquitoes. We loved it so much we recommended it to two other families.

Doesn't worth it at all
Didn't work with the mosquitoes of Quebec(( The one on the photo like many others stayed on me without any problem. The photo was taken after one hour and half of device operation at the same place.

Never go hunting without this!
I just works as promised. Windy conditions are not good for it but neither to mosquitos. When there is no wind it works perfect. We have mosquito invasion these days, yesterday I went hunting and if there weren't 500 mosquitos around me that constantly tried to attack, then there were none. I hardly could stop in order to take my Thermacell from my backpack. But then turning turning it on, 99% of the mosquitos have disappeared within 10-15 minutes. Just unbelievable, it magic! :D Of course 1-2 pcs will remain all the time but that's much better than 500.

Great product
I've owned Thermacells since I first tried one back in 1999, I think. As an outdoorsman who hunts spring turkeys and early deer, there isn't a tool I own that'd I'd put more value on than my Thermacells. They're lifesavers. I've left my shotgun at home, and still went to sit in the woods, but if I forget my Thermacell, I'll turn around and lose an hour of hunting to go back to get it. What I love about this new design they went back to a toggle switch instead of the dial switch, which could turn on if bumped. I also like the integrated belt clip. Great product, great results. I'm a Thermacell believer!

Customer service is amazing!
I made an mistake with my order, called Thermocell and a girl named Sarah answered, she was kind and understanding to me which is amazing, she even explained things to me that I didn’t understand. Thank you Sarah, I hope you are having an amazing day today!

Great for Dog Walks!
This product works very well. I had a mosquito infestation around my home for a period of time and needed something like this to safely take my dog for his walks. The only downside to this product is that it takes awhile to turn on and sometimes isn't always effective for large swarms of mosquitoes. Overall, however, I am very happy with the performance of this product.

Great features
I bought one for myself and my boyfriend to hunt hog at night. It is truly amazing!

I purchased the Radius should I get the Portable
I see that the portable, like any of the other Thermacell product work wonderfully, however before I purchase it, I want to make sure it will work for me. I'm understanding that it gives you a 15 Ft. protection, but will it work as I'm walking on a hike? or taking the dogs for a walk in the evening? I'm not seeing that in any of your videos. I think it will work if I'm standing still in one area without constant movement. Am I correct?
