Product Description

Mosquitos are no small problem - they can ruin a good time with painful bites, bothersome buzzing, and days of itching afterwards. Until now, sprays, lotions, torches, DEET and citronella have been the only options for fighting mosquitoes. We started Thermacell because we wanted a better way to fight mosquitoes. From humble beginnings, our team of entomologists, researchers, and outdoor enthusiasts has over 100 years of combined experience fighting mosquitoes. Enter Thermacell. For all your outdoor adventures, Thermacell Portable Mosquito Repeller is easy to use and provides hours of scent-free, mess-free, DEET-free mosquito defense up to 15 feet per repeller. With no cords needed, the portable repeller is ideal for hunters from the tree stand to the duck blind, as well as on-the-go adventures like fishing, camping, hiking and more. Our most advanced portable repeller yet, the MR450 features a rubber armored handle, belt clip, quiet ignition, and ZoneCheck, which provides a visual indication when the zone of protection is created. At Thermacell, our mission is to change the way the world fights mosquitoes, and we've been doing it for over 20 years. Headquartered outside Boston with distribution centers in Georgia, we're leading the way with better, worry-free, more environmentally friendly solutions to biting insects. With global distribution in 30+ countries and tens of millions of repellers sold, more and more people around the world count on Thermacell to make outdoor time even better.

These are great!
This is my 3rd Thermacell in 10 or 12 years (lost the last one last year), love the lack of mosquitoes when hunting. However the packing scheme by AMAZON was less than desirable, and seems the handling was a but rough. The unit its self was popped out of the OEM packaging and rattling around in the box. Mine came complete with a battery, the instructions tell you exactly how to install it, and what the light means.

My first time to purchase an item like this, the Thermacell MR450, hoping to replace the toxic mosquito repellent sprays that I usually have to apply daily. As a micro-homestead gardener I spend most of my waking hours outside in the garden but the mosquitoes in our area are relentless and brutal. I’m so happy with this product! Odorless, effective, efficient, easy to use, long lasting and most importantly, IT WORKS! Clips on to my garden apron, I just set it and forget it. At first it looked bulky but I’ve found that it’s not cumbersome at all and I can move around freely without worrying about being swarmed and eaten alive by mosquitoes. For reference, I also purchased the holster for the convenience of having extra cartridges and fuel on demand. This product is absolutely fantastic! So glad I took the leap and purchased it!

5.0 out of 5 stars Effective bug relief...
Reviewed in the United States on June 17, 2019

I bought this prior to an early June trip to the Boundary Waters Canoe Area. It was the buggiest spring in recent memory according to many. Fortunately, the week we went the temperature dropped twenty degrees, getting rid of many of the black flies and mosquitoes. On the still nights when the bugs were out, this worked well in clearing an area around the grille to allow six men to sit, cook and eat without insects driving us inside our tents.

The downside is that this isn't exactly cheap bug prevention, requiring new butane cartridges every several days with occasional use and pretty much a new repellent pad every day. Still, it worked to cover an area and kept us from having to use the 100 percent DEET repellent we brought along.

After 30+ years of living in the woods of Maine I've tried almost every spray, torch, and candle on the market. This is, by far, the least disappointed I've ever been in a repellent LOL. No, it wont work miracles in windy situations, but I can sit next to the river with it's breeze and experience significantly fewer bugs annoying me than all the other products. Slight scent. The belt clip is essential IMO. Too bulky and warm for a pocket. Had a bit of trouble figuring out if it was working or not at first because you have to be looking almost perfectly into the little window. Also ran the first mat way too long because it still had a fair amount of blue on it. Practice makes perfect!

I live in a tropical environment and mosquitoes are a real issue. I was somewhat skeptical that this would be as effective as Thermacell claimed but it's brilliant. Very easy to use and highly effective. I would suggest you buy the new 12-hour mats - I have the traditional mats that last 4 hours but the problem with this is that you have to wait till the mat cools down to replace it and then another 20 minutes after ignition for it to be effective, i.e., you'd probably be without protection for close to 45 minutes. You would really have to have two units - one that is in use and the second to have ready when the mat in the first one wore out. However, 12 hour mats eliminate this issue.

We took this camping while kayaking on a river in Missouri. It’s the first the we got out for lunch and when setting up camp. I was surprised how well it works! We could see the horseflies around us but they did not enter our circle with this. No biting flies, mosquitoes or other bugs. It definitely made this camping trip much more enjoyable. Downside, there was a lot of condensation on everything in the morning so it took the Thermacell a little longer to “fire up” after it got wet in the morning. Still worked though. Highly recommend!!

3.0 out of 5 stars there are limitations
Reviewed in the United States on July 4, 2019
Verified Purchase
The sales description on Amazon is a little deceptive. It says that Thermacell is "the trusted choice for the toughest conditions," and then it goes on to describe activities where action and movement is involved. It wasn't until I received the actual product and read the instructions that I understood the limitations. Thermacell is not effective where there is any air movement. It is severely limited when hiking or mowing the yard or if there is any kind of breeze. Performance is affected above 7000 feet altitude.

My first trial of the Thermacell was hiking. I was on the move, there was a bit of a breeze, and we were above 7000 feet. I was disappointed in the performance against mosquitoes.

In the yard, my biggest problem is with biting midges (also known as no-see-ums or gnats). The second trial was mowing the yard where I am severely eaten by these midges. I hoped the mower would go slow enough that the movement would not be a factor. It was a huge factor and I got all bit up, again.

My third trial was weeding, where I am mostly in one area, not on the move. Finally it seemed there was some relief, but I was also well sprayed up with a home remedy bug repellant, not DEET. I thought the pad was getting used up, turned off the Thermacell, and then I was bothered by the midges and mosquitoes. So I turned it back on, even with the mostly used pad, and it seemed better.

I will keep trying the Thermacell when I am in the yard and not on the move. I am just really disappointed that the limitations were not clear in the sales pitch.

Je suis tellement contente de mon achat! Ça fonctionne vraiment. Les maringuoins étaient en train de me rendre folle à chacune de mes sorties à l'extérieur. Maintenant, je n'ai plus aucun maringuoin autour de moi. Je l'ai testé encore hier lors d'un spectacle en plein air. Nous étions tous assis par terre et je voyais les maringuoins voler à travers la foule mais jamais aucun ne s'est approché de nous. AUCUN!! Je n'en revenais pas! Ça me fait plaisir de partager mes commentaires car c'est aussi en lisant ceux-ci que mon choix s'est arrêté sur Thermacell et je ne le regrette pas une seconde. Merci!
