The title says it all. Maybe it's me, but even when carefully following directions, it stuck together and became unusable - you can't get it apart once it does that.  It's very thin and when you pull the backing off, it immediately curls up onto itself.

The only one (single, so useless, sadly unless I wanted to walk around lopsided) of the 3 sets I got to work DID work - the lift was great.  Too bad :-(
