We got these refills for one of the little patio units. The unit works if you use it the way it should be. Not around food and it doesn't seem to be made for people to be walking around. It's made for sitting around outside. If people are constantly entering the bubble, insects will get inside.

These were refills for my Original Mosquito Repellent unit that I purchased two years ago. This is the best mosquito repellent device I have ever purchased (and I have tried a lot). This one just keeps on working and I can now sit on my porch again on summer evenings!

Happy with the product it definitely works to keep the bugs away. We use three at the same time, the Patio Shield and the Perimeter System simultaneously and it keeps a large area bug free. I’ve been recommending it to everyone and has been a game changer for time outside with my family.

I was sceptical at first but after using these on our patio I became a believer. I absolutely saw zero mosquitos and my son's playset was safe as well. I have now became a loyal customer and have even recommended this product to other friends and family. I ordered these with other products to bundle and i am very pleased with all the products.

Therma cell works. I've been using Therma cells for year's. While hunting and fishing In the the Arctic, Northwest Territories, Canada, and all throughout United States. It's a must when being outdoors. The way I enjoyed the effects of Therma cell the most, is at picnics in my own backyard and sitting on the porch's at night. It's hard to believe after all these years it appears to be Still the best thing I found for being outside and eliminating insects from the area. The only thing I would add is that you have to be patient and wait the first 10 minutes like the instruction says for it to start working well. I've recommended this product over and over to my family and friends they all agree it works like it says.

I would have given 5 stars but the fact that UPS could not get them here on the original date was a huge detriment. Not sure why anyone is still using them to ship product.

These are great, I had bought them as a Good Morning Amerida Deals and Steals the first time. Keeps the critters away. Need to stock up, pest weather is still here.

Wow! 120 hours all in a box! This was a great value for the price with the additional hours. It's always a bonus to upgrade to more hours because you typically save in the long run!

The thermacell is fantastic. I sit outside in the morning to smoke a cigar and have coffee. It got so bad with the mosquito's I would drive to a casino for my coffee and cigar. After buying the Thermacell NO MOSQUITOES!!! I love this product.

My brother loved it. They we’re getting by mosquitos and ants. Once he fired one up they all disappeared. A June-bug flew through the mist and flew erratically and then died. Stuff’s Awesome!!! 10 stars all across!!!
