Love Thermocell
Unit works great. Mosquitoes love me and this is a saving grace. I would give it five stars but the cover is terrible. Primary flap in the front can’t be used with the unit on. it either covers the front vent or the back vent and has no way of staying out of the way.

Disgusted longtime fan
I’ve been a staunch Thermacell supporter and customer for years. My original portable unit finally quit working. I LOVED MY THERMACELL! It worked and performed perfectly. Bugs didn’t want anything to do with me. I don’t know why it died because there’s not much to them. It would light up then die immediately. So I bought 3 new ones. The new design sucks! PERIOD! I bought a new 2 years ago and it never worked from the start. I had it on my yearly 10 day deer hunting trip. I got so mad at it I threw it against a tree! I HATE the new design. The detachable clip is the dumbest design I’ve seen. I’m very disappointed. I hope it actually stays running. At least the bugs won’t bother me even if the new design is junk.

Light-weight, portable, and it works
Light-weight, so it can also be hand help. I was walking my dog in the woods, carrying it along with me and I did not get one mosquito bite. That is amazing for me because mosquitos love me!

Great product
I am still using my original Thermacell that was purchased in 2010. Thinking it may stop working at any time I decided to purchase a back-up. The MR300 was an excellent choice for me. I rarely go to the woods or work in my garden without taking a Thermacell with me. If mosquitoes are a problem for you purchase the MR300.

Bye Bye Bloodsuckers!
If you hunt where there are mosquitos you MUST have one of these!! They absolutely work as advertised creating an invisible barrier around you that keeps those blood thirsty bugs at bay!! We hunt the marshy areas on the shores of the Chesapeake Bay - at times I will set up two Thermacells in my stand as the insane numbers of the mosquitos there can "carry you away" LOL

This works amazing!!!
I bought this for early deer hunting. First trip out I was sitting in my stand,never had a single mosquito. Shot a deer so I got down, put my gun and my mr300 in truck to drag my deer. Should have kept my mr300 on me. In the short time it took to get straps hooked to deer to pull out i was swarmed with mosquitoes.

If you are a hunter down south you need this! The scent doesn’t spook deer at all. Who ever invited this is a genius. Not a single mosquito bite over a hot humid bow hunting season. I will never use anything else in the woods again. Thank you Thermacell!!!

Swear by Thermacell but... South Florida
Dear Thermacell,
I love your products and have used them for years hunting, camping, sitting on the front porch, you name it! There’s just one thing. These mosquitoes in South Florida Recently mutated into modern day pterodactyls that are sometimes bigger than a penny! They laugh in the face of my 15ft force field!!! On the next go around, please make an extreme wafer that we can use down here. Also, something for gnats, horse flys and yellow flys would be really dope!

Almost works too well!
We took this on a 4 day camping trip to the Boundary Waters of Northern Minnesota. It worked wonderfully! A quick note, shut it off and leave it outside of the tent. The fumes continue to linger for a while after it's turned off.
