Product review (1 stars): IMPOSSIBLE to use if you've got hand pain, or wet hands.
I'm still using the original knob that came with my series 80 washer; lord knows I wouldn't buy the same replacement.

 I really wanted to get a warning out for anyone who has any kind of hand problem...arthritis, carpal tunnel, or just weak hands. This knob is IMPOSSIBLE to pull out if you have any of those conditions, or even if you have wet hands (& who's gonna have wet hands around laundry, right?). I got so aggravated I tried to drill a hole thru the knob so I could attach something to it so there'd actually be something grabbable to pull out. Drill didn't work, but enough gouging with a sharp implement got a hole thru eventually, & I threaded a ziptie thru it for a loop.

I HATE this thing. I'm sure the designers thought it looked sleek & snazzy; if all you want to do with your washing machine is stare at it, I suppose it's ok. Otherwise, it sucks.
