Product review (5 stars): My washing machine spins again!!
My washing machine spinner stopped working.  I called the washing machine repair service and they said $75 to walk in the door and additional for time and parts.  I watched a youtube video of possible DIY fixes and discovered that the coupler was probably the culprit.  Sure enough I saw a piece of white plastic on the floor when I moved it.  With the help of youtube I was able to change the piece for a few dollars and I didn't even break a nail.  Best money spent ever.  Product works perfectly and easy to install.
