Product review (5 stars): Fast delivery, works great.
Replacing the belt on my old GE dryer was fast and straightforward, coming from someone who had never repaired a dryer before.  This belt came quickly and I was up and running within days of realizing the belt had broken.  It's been operational for about a month now, no problems!  Save the money of getting a repair guy to do it for you.

Some associated advice from a complete n00b:  don't spray WD-40 into the drum bearing of your dryer.  Especially while it's running.  I was feeling good about replacing the belt and decided to deal with a little squeaking that I was having...it quickly burst into flames and I'm happy I had a fire extinguisher on hand (thanks amazon!).  Luckily nobody was seriously injured...and it still works!
