Disappointed
I've used other Thermacell products in the past which prompted me to buy this portable version. I had hoped that it would already come prepared to be a hands-free unit, so I was disappointed to have to spend additional money to purchase a holster and clip. My expectation from a portable unit is to ...

Lattern is really cool but the fills don't work
I bought this a couple of months ago love the lantern but the mult-insect refills for flies don't work. Seems like the Texas flies love it. I bought the lantern cause my best friend just bought one and it was really cool, while I was online I saw the refills for multi-insect so I bought a box of 96 now wish I had gotten some of both refills
Excellent Product
I purchased one of these portable Repeller's about 3 years ago and this item works like the day I purchased it. We use it when fishing at a local fishing spot (or should I call it a mosquito Sancturary). As long as there is no wind it works great and we are bite free.
No more mosquitoes
I have been using these products in Texas and Alaska for 3 years. I have sensitive skin so these are the best repellants for me. They are easy to use, very portable and really work well. I started with one and now have five of various models. I recommend them to everyone who is looking for a mosquitoe repellant. Thanks Thermocell for making this amazing product.
The Best Bug Repellent!
My son bought this for me for Mother's Day, he knows I spend most of my time outdoors. Before my Thermacell gift I would end the evening with multiple bug bites! Not anymore!!

I absolutely hate mosquitoes but the love meπ€¬ With ThermaCELL I can actually enjoy being outside and not get chewed alive!! I own 2 at the moment but will most likely buy more...I've never found anything that works like these!!ππβ€οΈπβ€οΈπβ€οΈ I've been a walking talking spokesman all summerππ€£ππ
Works Great!
I have bought and used Thermacell for years, I have 10 different models and they all have worked excellent, except one stop lighting which they replaced free of charge in two days!
Great product...but fuel cannisters non-recyclable
This product works great, and repels mosquitos as advertised! But I can't give it a full five stars because of the non-rechargable (and non-recyclable) fuel cannisters. I feel very guilty throwing your empty cannister in the trash, so limit my use of your product to a couple of times a month when we entertain, and use our screen house for daily use. I would feel much less guilty (and would use the product daily) if the cannister was rechargeable! Please tell your design folks to make this change. Thanks! John Collingswood, NJ
Did not last one summer
Was very happy when I found the lantern, unfortunately after 3 months it did not ignite anymore.....as I had still mats I bought another product, a handheld one....after using it 3 x week for 2 months, i found it one morning leaking out the fuel...huge mess on the wooden table and a full cartridge lost. Mats and cartridges are not cheap so I would wish that at least the pieces would last

Dual purpose is great
I have had the Cambridge for 3 years now and it always works. We like the 2 light settings, 1 is a standard white light and the other is a candle flickering light like a old time lantern. No mosquitos near us with this beauty.
Product seems to have changed
I've been using a thermacell on my patio for several years. The mats use to last 4 hours as advertised. I would go through butane cartridges quicker than I had to replace the mats, now it's the other way around. The mats are turning white after only an hour to an hour and a half. I'm not sure what has changed with this product but it's getting super expensive having to constantly purchase more replacement mats. So disappointed because the product works great it's just not lasting the 4 hours as advertised anymore.

Hi, The MATS have two chemicals on them. the first chemical is the repellent. The second chemical is a timed released blue dye. The blue dye, can fade in some cases in a short period of time, but the repellent remains on the MAT for the full 3-4 hours. Our testing shows that after 4 hours, 25% is still on the mat. You can leave the Mats in even if they turn white a bit sooner than you expected. The environment can cause this to happen as well: heat, humidity, wind. and altitude. We recommend just leaving them in for the full 3-4 hours even if they seem to be turning white. if you have any other questions, please feel free
