Living proof that people will come to the defense of any good product, sponsor of the board or not.

Dude, toss some sand into ANY product with a tight metal to metal fit, like roller or ball bearing or even a bushing (never had an Abu so don't know how they're built) and see what happens.

For that matter, put some in your knees and see what happens.

I can think of a quite a few other really BAD places to get sand, but this'll do.
