Had plumber install the faucet.  One of the replacement cartridges (part # 1224 on the hot water side) was cracked and as a result, the handle can turn 360 degrees, although the water does turn off at the point where it normally would stop.  I called to get a replacement for that part. No option to talk to a person or leave a message, even if I'm willing to hold.  Only option offered was to request a call back from customer service, and the first available slot is not for 5 DAYS.  Not only that, but you didn't indicate in what time zone my assigned time is.  So being in Pacific time zone, I may have to be available starting 3 hours before my assigned time. This is TERRIBLE SERVICE!  (Note:  I'm getting a side bar that says to keep my review focused on the product, and if I want to share feedback about customer service issues to contact Moen directly.  I TRIED.  The lack of service is worse than the broken part.)
