Disappointed

I loved my thermaxell, until it just quit. It began starring without having to push the start button then a few days later it just stopped all function.

New Model Not As Good As The Old

Bought two of the original thermacell when they first came out. They worked perfectly and kept the mosquitoes away. This hunting season I bought a new one after the bottom that covers the butane, broke. The new model does not heat up enough and DOES NOT keep mosquitoes away. I got eat up. The next morning I used my old one and it again worked flawlessly minus the bottom cover.

These Are The Greatest

I use them for early fall deer hunting, I am able to sit in my deer blind all day long without a mosquitto, just a reminder, pad need to be replaced every 2 hours

Does Not Stay Lit

I bought this in July 2025, and the little red light letting me know this is lit no longer lights up, and I keep having to push the start button because it doesn't stay lit.

Doesn’t Work Like The Original

I have been a long time Thermacell supporter, but I have bought four of the 300 series for hunting I have a lot of the others I’ve never had a problem all four of these 300s I cannot keep running. They will fire up for a quarter second and then go out too many times they’ve left me stranded in the south Florida mosquito woods, swatting mosquitoes cussing a brand new thermacell not sure what the difference is. I have used multiple different cartridges for propane to make sure it’s new and fresh with no difference. i’m not buying another 300 series that is for sure.

No Glow

IH had several of these mosquito repellent devices over the years. But this time I went and bought another one, but it would not burn. Luckily I have my receipt returned it.

Not Very Happy

I bought this device 2 months ago and now it will not turn off and it empties the fuel cell just sitting.

Works Perfectly!!!

Those is my second one I've bought, they work great

Works Good.

I never go in the turkey woods without it. I also take it with me fishing just about every time.

Quality Has Gone Too Crap

Bought as a back up to the old one.....The new one won't light....The new one won't light...Can you hear me now!!!!! Brand New Brand New Can you Hear me now

Does Not Come With Clip

Does not come with clip to attach to belt or pack .

Was Not A Believer But Wow

Read the reviews but still was not a believer. I purchased the MR300 hunt pack to try on a upcoming fishing trip to Canada. Had it with me when I was in one of the National Forests in MN to check out a remote trout lake. Had my lantern burning with citronella and cedar fuel yet the mosquitos were still super thick. Went to the truck, opened the Thermacell box, installed the fuel and pad, turned it on and one click the unit started heating up. Within 10 minutes there was not a mosquito around me. When I would walk out of it's range, I would be covered with them again. Once back in town I told 36 friends, family, and coworkers about it. Since that time, at least 18 of those people have purchased them. Great product. Get yourself a couple.

Aesome

I have been using the MR 300 for yrs with no issues. I used it last spring in SC while hunting hogs. When the sun goes down mosguitos come out and sounded like vultures going to a road kill. I turned on the repeller and five minutes later they all left

Pads Became Worse

I agree with other reviewers that te pads have changed. They turn white after an hour. Not after 4 hours. Please Therrmacell react to this. What has happened? Isn't it a problem that they turn white so soon. Will they still work? Have they changed? What is going on? The refills already cost a fortune and now they work just 1 hour. It is the only device that works! But normally people cannot afford it anymore like this.

Poor Performance (Repeat)

Worked one time. Would never light again. My third purchase. Three times a charm. Expensive lesson learned. I've bought my last thermacel
