Product review (2 stars): Metal insert breaks loose
The seller had very good response time and shipped the item quickly. It was also packed well. I would buy from the seller again - just not this item

The coupler only worked for about 8 wash cycles. The metal insert came loose in the center of the coupling and now spins freely without turning the transmission shaft. I took everything apart and pushed it back into the plastic part and used Loctite Epoxy Plastic Bonder to try to keep it from coming loose. It slid out of the plastic again on the first cycle and destroyed the grooves that hold the metal into the plastic so I can't just push it back in again.

The part is listed as having a lifetime warranty, but I don't really want to take the washing machine apart again. I ended up getting a good all-plastic coupler off a washing machine the neighbor was disposing of.
