I have used it for at least 10 years... it is a very good product. I have taken guns that I thought just would not shoot anymore, and brought them back from the dead with exceptional accuracy. When I have a rifle that I have not cleaned in a while (mine are USED a LOT) and notice the accuracy falling off, I run a couple of series of WipeOut through the bore. After a couple of fouling shots, groups invariably tighten right back up.
I started using it after an article by Chuck Hawks... he was spot on.
