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.

I wish I would’ve read the reviews before I purchased this product. It worked once. Took it camping with us and could t get it to work again. We bought a bunch refills and can’t even use them now. 😣👎🏼

Every Thermo cell unit I have bought doesn’t last. They work great, when they work, but they always break. Bought the little round one about 2 months ago from Lowes, as of today broken.

Was so excited about this. Pulled it out of box, followed all directions and...nope it doesn't work. I called and hopefully they will replace it as it was a gift.

Cannot get product (brand new out of box to ignite. I purchased it several months ago, but never used it.) First attempt, the orange glow appears for about a second and then disappears. So not happy with this product at the moment.

I love both patio shield Thermacell product, I have not been bit since I bought it, however the repellent pads do not last 4 hours. I get maybe an hour to an hour and a half out of them.

This patio repeller is great for summertime hangouts and with all the summer activities happening this year I plan to use this quite often. The size is good for travel and allows for you to setup in smaller or a bit bigger areas.

Simple to use, simple design. This is our second repeller and we've been happy with both. The weather has just turned cooler here so we're not seeing the activity but happy to have mosquito coverage on both our porches.

Bought this and used it for an outdoor gathering near our mosquito infested back yard - amazingly there were no incidents of mosquito attacks! Who would have thunk?

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.
