Product review (5 stars): Fixed my dryer
Got my dryer back up and running in short order.  These belts seemed super expensive from local sources.  This price seemed a bit too good to be true, but it came quickly and was exactly what was needed.

Couple of tips on installation that aren't totally obvious from online instructions.  There are quite a few youtube videos that detail this repair, and for the most part they are great, but the ones I watched showed the repair being done from the front of the dryer.  You do have to remove the front panel to remove the old belt and do the initial installation steps, but after putting the new belt in place, move to the back of the dryer and take off the access panel at the bottom of the back panel.  This gives easy access to the motor and pulleys.

Also, when you put the belt on the drum, there is a groove in the drum that you would assume the belt should be routed into, but goes outside the groove (just outside).  I thought the belt would eventually work its way into the groove, but it stays put.  If you the belt gets into the groove during installation, it will not fit around the motor and pulleys correctly (too much slack).
