Understand you can only use these for approx 50 uses and they get brittle. But mine have held up well and keep them in Zip lock bags!

The item itself seems to work great. I traded it off to a friend since I had no use for it. He says it is as good as the the ones that he had for a while now.Just a side note as to why I bought it.... I had ordered it as a combined offer with a discount with an electric furnace. The furnace which shipped separate never arrived. I won't blame Amazon like others do for shipping issues. UPS/FedEx/USPS was the problem as normal. I guess in the end it was for the best. It would probably be one of those things you buy and use once. Then you find it later and ask yourself why you spent the money on that.
