Product review (4 stars): Easy Repair.
The kit was exactly what was advertised.  However the pulley was different from what was in my dryer (which I discovered upon opening my dryer). The wheels appeared to be the same but I did not change them due to having to take out the barrel.  I was able to replace the belt with ease and now my dryer is back in business.  I have the extra parts but it only cost me $21 for this repair.  I'll take that over what a repair man would have charged me.
