Product review (4 stars): Not bad at all
I've never changed a belt on a dryer until now. The process was easier than I thought it would be, especially after watching a couple of U-tube how-to's.  Just take your time, an extra pair of hands for 20 minutes helps a lot.

A socket wrench,  screwdriver and an 8" block of 2x4 for a temporary support for the dryer drum is about all you'll need... Along with a bit of patience.
