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.

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.

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.

Disappointed
I have absolutely loved all my thermocell products in the past, never had a single issue with them. I recently bought the mr300 and I have had nothing but issues, I can’t get it to stay lit. It will light for 5 seconds at a time and go out. I loved the old style, it would light no matter what. I’m very disappointed in the quality of my new thermocell

Perfect for my hunting needs!
I bought this and was concerned that it was just a device with minimal effectiveness, but I am very happy with it’s ability to keep the bugs away and not spooking the deer away. I did purchase the earth scent pads for my ThermaCELL.

Hunters best friend
My wife and I have been using thermocel for a few years now and we couldn’t hunt without them. We hunt a swampy area and the mosquitoes attack us the minute we get out of the Polaris. We turn on the thermocel and within minutes they are gone. We love the units

I bought a second one because of how well they work. I used this in Canada to harvest this black bear.

Worked great for ONE SEASON.
I’ve purchased these in the past and have always been extremely impressed. Unfortunately the last two I purchased will not stay lit. They’ve been properly cleaned and maintained - I thought perhaps it could’ve been old butane? So I purchased a new box , still nothing.

I always thought it was great...
This is the second season that I have used my 300. I always swore by it, and recommended it to anyone that asked about it. Those were usually times when we were on our deck, by the fire ring, or while I was on my tractor during the day. However, last week we were eating outside on our deck , and I had my Thermacell running. Suddenly, my wife laughed, and told me that there were two mosquitoes flying within a foot of the unit. I was extremely skeptical, and had to see this myself. I went back to our table, where the Thermacell was hanging from our umbrella, and watched as mosquitoes were flying around and by it like it wasn't even there. I figured maybe it was a weak pad, as I had used this one for an hour or so earlier in the day. No harm, no foul, things happen. Tonight I had taken the unit with me, into my yard, with a fresh fuel cell, and brand new out of the packet, fresh pad. I hung the Thermacell on the side of my tractor , and went back inside for a few minutes, to give it a chance to build it's zone. I went back out, and began working on the tractor, and sure enough I was being eaten alive, and there were mosquitoes flying merely inches away from the unit, that was actually emitting a faint hint of smoke from the pad! I don't know what has happened, but this product no longer works for me. It ignites, heats the blue pads, and is occasionally hot enough to smoke a bit, so it is functioning, but it is most definitely not doing it's job.

Brand new unit and it doesn’t work.
Purchased the MR300 as a second one to use for deer hunting as I keep the older one in my turkey vest. First time with it in the woods and it won’t light. I can hear the gas flowing when switching it on ( and it’s a new full cartridge), and pushing the ignite button lights the gas, but it won’t stay lit (no glowing from flame in the viewing window). Quality of these new versions is no where near that of the unit I’ve owned for almost 15 years. Very disappointing.

New design is not an improvement
I had the old unit with the turn knob to turn on the fuel and the small button to light it. It worked great for many years. When it finally quit working I immediately bought another only it was this “new and improved” unit. Well the little switch for the gas gets turned on all the time when not in use and empties the fuel cartridge. The bigger ignition button requires multiple clicks before the gas lights. If I ever find the old model I’ll buy as many as I can find cause you can’t be in the woods in South Georgia without one of these. If it worked why change it.

Miss the old thermacells
Took this hunting twice in Florida and mosquitoes were landing on the thermacell even while it was on. The new thermacells don’t work like the old ones did. Sad. Would not reccomend buying. This review probably won’t even go up.

Great Product
Great product for hunting. I always take a back-up with me on each hunting trip. Love the new switch vs the dial. Only downfall I see is they put a blue swish and bold white letters saying "THERMACELL" on a camo holster. Got a feeling some marketing genius that never went in the woods came up with this idea.

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.
