I bought this unit at Sportsman's Warehouse just prior to a camping trip since I saw it was highly rated. I inserted the butane cartridge, slid in the repellent insert, gave it a few seconds, and clicked the start button 5-10 times. It lit up and I verified that the flame was consistently on. Everything worked the way it was supposed to (I could occasionally see the vapors burning off the repellent insert, and it slowly changed from blue to white). I initially had the unit sitting right beside me on the armrest of my camp chair, but I was getting bit on my legs. So, I decided to place the unit directly on the ground - next to my feet. When I did that, I got bit on my arms. For me, personally, it seems that this unit is only good for about 2 feet - maximum. I would ideally have one on the ground by each foot and one on each armrest. However, at about $25 each, I don't think I'll be buying four of them. I'm disappointed since one is advertised to handle a 15 foot area.

I bought this sprayer today to take to the lake with me fishing had it running for over an hour before the mosquitoes came out and the mosquitoes still swarmed both my husband and I just as much as without this thing running in fact I had some mosquitoes swarming around mosquito repeller itself....WASTE of money!

I bought this product for now hunting after sitting in stand getting ate up. Used product the very next morning and mosquitos were gone. Thanks for a great product that does what it says it will do. I'm from Louisiana highly recommend if you hunt in the south and don't have this product with you you need to get one.

Love the cove and the storage for refills. The unit as always is great and getting better. I use them when hunting, fishing, camping and working. I work out side all day every day and they are great. No sprays that run into eyes and mouth when you start sweating. The only things I would like to see changed. The cover flap, no way to secure it when wearing on belt and unit is on. The other is the colors of the print. As a hunter I want to blend in, The blue and white print when cover flap is down dose not do that. other than that. Great product as always form a great company.

This is my 5th Thermacell Repeller and it will stay in my truck. The others are a Cambridge Lantern on the patio, another Cambridge Lantern in the camper, an MR150 attached to one of my tackle bags, and a Bristol Lantern in the garage. That should pretty much explain how much I like Thermacell Mosquito Repellers!

We’ve used this for picnics, camping and backyard. Works great with new insect pad which is supposed to last 4hours or when it turns from blue to white. After only using one partially we saved it but it did not seem as effective after being exposed from its packaging. I’ve bought two of these and gifted a patio unit.

I bought this hoping I could go out and garden without wearing long sleeves and long pants. NOPE.....I have too many mosquito bites to count. I felt the heat off of the unit and the orange light was on but if the unit was working it did NOTHING for me.

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.

Mosquitos love me. I have one of these and an older 150, I use them whenever camping in Dubai, UAE and in the woods of Wisconsin. They really got tested to the max when I was making a wildlife documentary in the bush in Chad, Africa. When in a Malaria-rich, remote locations for weeks on end, you need a product that you can rely on. They worked a dream. When one ran out of gas- unknown to me, we were set upon by mosquitos. As soon as I replaced the canister, they were off ! Great customer service too.

I'm a hunter in SC and the majority of my time is in wet, swampy areas-so the mosquitoes are a nightmare to say the least! The Themacells are a lifesaver! I've had several different hand-held repellers and purchased this one earlier this year, to add to my arsenal-and like all the others, IT IS GREAT! I really like the new camo carrying case as well. I highly recommend these to all my friends!
