For me - every fkin' weed whacker I've ever owned. I've never found one that wasn't a pita when it came to keeping string on it.
I don't like either of my Lincoln grease guns either. It may not be the fault of the gun. Thanks to Paul's suggestion I'm getting a Lock-N-Lube end for one of them. My birthday is coming up. I'm telling MrsWD I want a Lock-N-Lube. Can't wait to see the look on her face.
