I've noticed the same thing that happened to you. I have an Awesome Flip, that does have quite a few games, and a S&D that has about the same # of games. I clean both the same and very often, but while the S&D has retained the same reaction, the AF has lost some hook. Oddly enough its not really "dead" in the sense that I've come to know, it still has some angularity left and just as good continuation as it had when it was new. I have seen more problems with activator than I have seen with pk18. Although as compared to many covers, activator has a long shelf life, pk18 just never seems to die.
