Product review (5 stars): The best $20 I've ever spent!
This is the best $20 I've ever spent. The unicoupler on my discontinued Maytag portable dishwasher leaked badly for about a year, then would not stay attached to the faucet at all as of last week. I called Maytag, who could only offer a discount on a new portable dishwasher -- a "discount" that would still result in $640 purchase.

My local appliance repair guy would come and diagnose the problem for $100. Yes, not FIX the problem, diagnose it. I didn't need a diagnosis, the unicoupler wouldn't stay attached to the faucet. That's the diagnoses.

After about 2-3 hours of internet research, stumbled upon these replacement parts and figured I might as well try it before plunking down another $600 for a dishwasher -- the one I have is only 8 years old.

In 20 mins, my unicoupler was attached -- still with a very small leak but it always had a small leak. I'm not necessarily a handy person, besides getting the teeth to not fall out as others have mentioned this was easy peasey. As far as I'm concerned this part put $580 back in my pocket.
