Product review (1 stars): Buyer beware.  Product is substandard.
Rubber rollers fit snugly and had a bad smell that took a couple of weeks to dissipate.  Rollers only lasted five months before starting making noise.  When I disassembled the dryer, I found the rollers had  disintegrated.  Do not recommend this product.  I  purchased the Whirlpool 4392067 Repair Kit, part did not have a odor and part fit perfectly.
