Product review (5 stars): Cheap, 5 minute fix. Easy peasy!
This was much easier to replace than I thought it would be based on the reviews I read. My dishwasher had been leaking from where the hose attaches to the sink for quite some time. I figured I'd have to replace the entire hose. Nope. This fabulous piece did the trick and took me all of 5 minutes to replace.
