Product review (5 stars): Used to repair a month ago & dryer is still working great!
So far has worked perfectly to repair my dryer.  I only needed to replace the belt, which had broken, and the idler pulley, so that's all I replaced at the time.  I've kept the extra wheels in case I need them.  Repaired the dryer 4 weeks ago and it's been as good as new since then!  Highly recommend! (I searched and found a You Tube instructional video to walk me through how to do this on my particular dryer.  I recommend using that if you're not experienced.)
