Small Radius These coils definitely work! But the radius is pretty small. If you're planning on staying at a table or in another smaller area, they're a great choice, but they won't cover a whole backyard. If you have A LOT of mosquitos, like I do, you'll notice there are fewer, but they won't keep them all at bay (will anything?)

I use it when camping it works. I love to use when out side on deck it works i have never been bite sense i used this product.

Keeps Mosquitos at Bay I think these work great. I didnt like having to worry about kids running around with this lit as they could gave knocked over. But it really does keep the mosquitos at bay.

It does work Tried this item out of curiosity and it did work. I put 2 could on my back porch and it seemed to keep away mosquitos. My porch isn't to big and it's screened in however for a porch or some place not screened in may take a few extra coils.

My safety valve Love this stuff...it keeps me safe and well wespeicallyw hen I am out int he yard and on my property...it rocks the protection I need and want,.

Skeptical - proven wrong I was skeptical but this product really helped us. We live in the middle of nowhere but we also have a lot of family gatherings. Mosquitos are the worst, so when we came across this product we decided to try it and it really worked. Mosquitos were still around but this coil helped keep them from being on everything and everyone in the area.

Love these! I've used these since they came out years ago, although the look has certainly changed. I like these better than candles since the smoke gets blown around a bigger area. They definitely keep the bugs at bay and smell decent. Keep away from animals when lit since the smoke can irritate their eyes.

No more mosquitoes I used these last night on my balcony. I was sceptical, but greatly surprised how well they worked. They covered a large area and lasted for hours. Not one bite on any of us Will be buying these from now on.

These really work I used one n it kept the bugs away
