Product review (5 stars): Easy to change and I saved money.
It works good in my dryer the only hard part (if you can call it that) was taking the top and back panels off to get to the part.  I did look at the other rollers and belt which looked OK but I'm not looking forward to having to change them.  When I do have to change them I plan on checking here first to see if they have the parts.

Good price on the part when I bought it, easy to install and saved money by doing it myself.
