Review on 2-Pack Portable Mosquito Coil Holders - Perfect For Outdoor Use, Pool Side, Patio, Deck, Camping & Hiking! by Tara Rodriguez

I put out two on a 12'x24' porch on the Fourth of July. I had been the victim of quite a few mosquitos the week before and didn't want 12 people to be miserable. These coils worked fine. I placed them flat, one at each end of the porch. The smoke was noticeable, but not irritating. I would buy again. But won't need to any time soon because less than half of each coil was used for a five-hour party.
