There is a smell to the fumes. It does not work on flies. They still come. Mosquitoes did stay away after several minutes

The Thermacell Patio Shield Mosquito Repeller works really well and I am planning to purchase another one.

Once this product arrived, I brought it on vacation with us to Cape Cod. I used it every night out on the deck and it worked flawlessly!!

Love this! Mosquitos always find me, with this product, I can be outside without dealing with getting bit. I even bought a second one for our deck.

I've owned other Thermacell's for hunting and this Patio is just what I thought it would be. Keeps the mosquito's away!

I have been doing alot of yard work landscaping, I put the Thermacell units around the perimeter and no more bugs!!

Excellent product. Worked as promised. Order additional cartridges however not happy that they will not arrive for another month. What's the use?

The only repellent that has ever worked for me. The 4 friends that have I have recommended it to also agree.

This worked for us!! My husband is a mosquito magnet, but this device kept them away!! It allowed us a peaceful, bite-free evening on the deck.

I had my doubts about this working but it did and really well. Even the dogs benefited from it while we were camping in the mountains in Colorado.
