I have two of these. One looks like it was never used. There are no marks at all where the socket goes and zero slop in the head. The other one I just picked up and has some play. The clicks sounded soft so I completely disassembled and stretched the spring just little. It helped but it's no where close to the sound of the other one. Is this normal or just a sign of a lot of use? I used the same lube on both so that's not why it sounds different.
