Product review (4 stars): Good product, good price.  Not fan of the rounded sleeve design.
More reliable than the rubber hoses provided with our new washing machines.  No leaks on install.  Only gripe was the rounded sleeve where I had to use channel lock.  In tight spaces, turning the sleeve was awkward and caused slippage.  I would have prefer a hex nut design where I can use a crescent wrench for better leverage.
