We believe in fixing appliances but as everyone knows, that's not easy now. We've ordered appliance parts online so we have some experience with a couple of companies but Appliance Parts Pros is the best company we've ever used. The diagram of our blender was easy to read but the how-to video was why I give you all a 5 star rating. Without it, we wouldn't have been able to fix our blender. The metal plate holding the coupler was hard to remove. It looked like it was designed to be part of the unit so without the video we wouldn't have applied force with the screw driver. The part we ordered came faster than we expected and the price was very reasonable. We are enjoying our blender again!! Thank you.
