They work well in a low or no breeze situation and cost little at Wal-Mart.
Note: While doing a search for this product for you, I came across an article talking of the horrible carcinogens you will subject yourself to by using this product

). Just thought I'd let you know it is there:rolleyes:.
Happy Camping!
