I bought it a month ago and I still got bugs around me, but in less quantity. So I'm not sure yet if it is worth spending money for the refill which is quite expensive.

I LOVE MY THERMACELL. WE LIVE NEAR QUITE A BIT OF WATER & WETLANDS. IT DOES AS ADVERTISED. WE ARE ABLE TO SIT OUTSIDE AND ENJOY A MOSQUITO FREE ENVIRONMENT

I have been battling mosquito's all summer and a friend gave me the info for the patio shield...wow!! Now, it's a totally different world to me. No more bites! How did I ever live without this fantastic gizmo??

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.

Bought this last summer. My wife hated starting outside in the evening as every mosquito would find her. Now my wife will stay outside with nary a bite. Thank you Thermacell!

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.

We have a trailer in Muskoka Ontario bought a Thermacell off a friends review. Everyone in the park has at least one. Within minutes of turning it on the bugs are gone, black flies and mosquitos stand no chance!! Great product

I've been using the outdoor units for a few years and love them. We recently purchased a new home with a large patio. I just start the patio shield up and enjoy my backyard! It's attractive and extremely efficient!

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 bought this 8 days ago from Walmart.living here in northern Maine their is no shortage of mosquitoes and patio shield rep I have taken back my patio am planning on buying 2 more for outside camping and picnics thanks again for the patio repeller
