Product review (5 stars): Good but...
The rollers I received were all black, not the red ones pictured in the item description. The rollers I was replacing on my Whirlpool Duet dryer were also red so I was a little surprised at the all-black rollers I received.  (Seller did answer my question quickly and said the manufacturer randomly changes the colors).  Anyway, the rollers are working fine as replacements.  Only problem I had (and its not seller's fault) is the idler pulley roller in this kit was too small for my unit. I have a Whirlpool Duet GGW9260PL3 dryer.  The idler in this kit did not fit onto the axle. The description did not specifically say it worked for my model # but it appeared the same so I took a chance. I got another idler pulley from a local parts place.  (The local parts place looked up the replacement idler pulley and came up with the same one in this kit, but it does NOT fit on a Duet model). I got lucky because he had an old Duet in the back and just pulled the idler off and gave it to me.

The belt and rollers in this kit are working great and the dryer is purring like a kitten again.
