Fairly simple it doesn’t work ! I’m covered in bug bites. And before you send me a lame message asking me to make sure it was working properly please save your breath. Light was on and the pad was brand new.

We swear by the effectiveness of Thermacell mosquito repellers. We have used two of the lanterns for several seasons, but recently added a Patio Shield for our patio and it is well designed and works great.

As always, the Thermacell never lets me down. Just as the weather is changing and the bugs decide to come out after a rain, the Patio Shield kept me bite free while we were enjoying the cooler weather.

The first few pads works for about 3 1/2 hours each, not the 4 hours as advertised. We bought refills. We used the first refill and it only lasted 1 1/2 hours then the pad was white.

I bought this a month ago and it does not repel mosquitoes. I waited to buy and finally decided I would try it. Wasted my money on unit and extra pads.

I used the Patio Shield in my backyard and was pleasantly surprised by how great it worked. I was not bitten once and was able to relax without the smell from a candle or incense. Whole heartedly reccomend this product.

I had my reservations about buying this since I had tried so many other products to no avail but I'm glad I did give it a go. It works really well in fact I'm going to buy at least 2 more for my back yard.

Love the Thermacell products, works great on keeping them nasty mosquito's away! Great for camping, fishing, hanging around the back yard or any outdoor activities. Highly recommend ;)

We bought this hoping it would help with the mosquitos but it DOES NOT. It repels NOTHING! We bought the thermacell along with a box of refills and it was definitely a WASTE OF MONEY! Will NEVER recommend this product to anyone!

This product worked great. We were at a friends and always get eaten alive by bugs but not after using your product. It was great and bug free. I even bought another as a gift for our friends.
