Susan P Albuquerque , NM September 20, 2015 The drive coupler on my blender was stripped and needed to be replaced We ordered a new drive coupler and it was incredibly easy to replace just by unscrewing the old one and replacing it with the new one. It took less than 2 or 3 minutes and saved what otherwise was a perfectly operating blender Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
