Product review (5 stars): Way better than the original
This replaced a 15 year-old plastic knob that had a pot-metal insert.  Since in every use of the washer, you need to pull, push, and turn it, the plastic eventually broke.  This replacement design is all-metal with a rubber covering and will no doubt outlast every other component ... as it should be; there's no good reason to under-engineer such a simple, yet critical part!  Note: the OEM supplier wanted literally10 times the price to replace it with (presumably) another plastic knob.
