Product review (3 stars): As advertised . . . sort of
Description says "and associated parts".  I assumed that to mean the little triangular retainer clips that secure the idler wheels.  Never assume . . .  Good news is that my local hardware store had some e-clips that were a suitable substitute.
On the positive side, I can't remember my dryer running so quietly.  Would have given a 4+ if not for the lack or retainers in the kit.
