redsevnI bought 2lbs on the last drop, and I'm tempted to get more on this one. This stuff is a blast! Just messing around with it, molding it into nonsense shapes, is a lot of fun. Not worried about wasting it, because I just heat it up and start again!
One tip I found: If you mold it into something thick, it's going to take a while to heat back up again. This is obvious once you think about it, but that 1lb cube @redsevn mentioned would take a LONG time to reheat!
