I bought the portable repeller over the summer to use while in the garden. I had purchased it in hopes of decreasing the black flies, knowing that this product is more effective on mosquitoes, as I was pretty desperate. To be honest, I'm not sure whether it was helpful or not, but to be fair it was a terrible year for black flies! I will try it again next summer and see how it goes.

Great product
I bought the MR300 yesterday morning, 10/13/2019, and used it for the first time yesterday evening. It works great! Down here in East Texas we have huge skeeters that will drain you of your blood quickly and this product keeps them away. It also keeps them "no see 'ums" away also. This morning I didn't use it and the skeeters were ready for breakfast. All I can say is that it works and wish I would have gotten one sooner.

Great for Hunting
I Bought the Thermacell for hunting due to the mosquito EEE virus in my area of Michigan. It has worked well so far. However, there isn't even a place to clip a lanyard to hang it. The belt clip or a lanyard loop should be standard on all these portable units. I'd give it stars with an improvement in how it can be carried.

Great for hunting and fishing
Work great but I don't understand why you would sale this without any way to attach it to yourself! It's says portable repeller,but no holster or belt hook nothing. I see the others have holsters but not this one!

They work, period.
I have two, one I keep in my summer pack and the other in my fall hunting bag.
Can’t say enough good things about them.

I have used this product extensively the past two years. It works great he past. I use it in the early hunting season and in thick wooded areas. I am never bothered by mosquitoes. I highly recommend that when you need refills you use the Thermocell brand refills, the off brands do not work nearly as well.

Works as advertised, refills pricey
We bought a couple of these after our neighbors introduced us to them at a backyard fire. I've been using them every weekend for the past 3 months (over 150 hours) and my only complaint is the cost for replacement pads and butane cartridges. These definitely keep mosquitoes away. I can honestly say I never get any bites when the Thermacell is running. Sometimes you will still get gnats, ticks, and other nuisance insects, but no mosquitoes.

You only need to have 1 running as long as you remain sitting still. We project movies and ball games in our backyard and 1 of these usually works well for about a 15ft radius (30ft diameter circle) of neighbors. When we go hunting, we usually carry 1 per person and just latch them to our packs. They don't seem to distract game, but I haven't gone deer hunting yet.

Pads say they last 4 hours, but they usually turn white and start getting pretty hot well before that (this goes for regular pads and/or earth scent). 3 pads probably gets me about 10 hours of continuous use, but if I almost always put a new pad in when I start a new session. Half-used pads that are left in the Thermacell are usually wasted. The butane cartridges seem to last about 12 hours (as advertised), so there's no need to replace them as often.

There have been multiple times I've forgotten to turn it on before the mosquitoes started, which has resulted in dozens of bites - so the mosquitoes are definitely active. A few months ago it was about 95 degrees and 90 percent humidity, while we went mushroom hunting through the woods. Mosquitoes were everywhere and neither me nor my buddy got any bites. We would just walk through clouds of mosquitoes without being noticed.

Highly recommended. I don't like taking the time to review products, but this one really does work so it deserves being reviewed. Do yourself a favor and buy the bulk refill packs because you will go through them faster than you expect and they are much cheaper than the smaller refill packs.

Keeps mosquitoes at bay
I first heard about Thermacell about 20 years ago while hunting in lowstate South Carolina. Some other hunters told me of this device that kept the hoards of the swamp mosquitoes away. They told me I could buy one at a local gas station, where I went and bought it. To my amazement after I started using it, I was no longer lunch for these pesky bugs. I have since bought more over the years and just purchased 2 more. 1 for myself and 1 for my son who hunts with me. If you don’t have one, you need one.

It really works!
Took it with a Backpacker as we had been warned the area was terrible for mosquitoes due to the wetlands around the campground. We ran both and it took about 10 minutes and the bugs were gone. There was a light breeze but they worked exceptionally well. My sweetie gets eaten alive and can say she had a total of one bite. One thing we have learnt is don't let them run out at the same time! Within seconds of shutting them down the mosquitoes were back and making up for lost time! I'm so happy I'm buying another! The group we were camping with have already bought or soon will as everyone was convinced how well they work. The others had brought coils that did nothing but smell.
