Product review (4 stars): Good deal
Works as expected.  One would hope that someone would make a better washer dog but no one has yet. I guess you would rather have this part fail instead of stripping the teeth on the inside of the agitator.  I bought an extra set and would purchase again.  This is keeping my 12 year old washer going at a low cost.
I have to also give the seller a thumbs up for sending me another order since the first shipment never showed up and could not be tracked.
