Product review (4 stars): I colored the handles using red and blue paint pens so that I can easily identify cold and hot
Installed these for my washer and dryer.  These appear to be quality ball valves which should last a lot longer than the old ones.  The old valves that seized up due to  mineral deposits.  Ball valves  generally don't have issues with mineral deposits.  I colored the handles using red and blue paint pens so that I can easily identify cold and hot.

The only issue I have is that there is a bit of water flow noise when water is flowing ( a common issue with ball valves.  However that only lasts a few minutes when I use the washer and doesn't bother me.
