They put Moen faucets in my house when they built it, and the valve in the shower faucet needed to be replaced in less than a year, so I wasn't happy with the quality of it. The shower didn't get used that much since it's in the second bathroom, but still...less than a year? (I couldn't get hot water to pass through it).
I replaced the valve myself, it was about $35 and so far no issues. I'll probably look at something else if I replace the other faucets because of that.
