I have used it for years. I am not going back to pinning. be careful of overspray, I spread "painting sheets" around the edges so I don't get any spray on the carpet, floor, etc. Lots of ventilation is important, don't use too much spray. It helps if you have a helper for lap size and larger. I have trained my DH very well as well as my sons girlfriend. They have even done a few with my watching!!! When you have two of you working it goes really fast and smooth. My favorite is the 505 spray, which unfortunately is a little more expensive.
