Gerber is a brand name of Globe Union Industrial ( Chinese ) Faucet Company. The same company who brings you Glacier Bay, etc. The quality is actually decent for the price. The question is what happens 10 years from now when you need parts?
I don't object to skimping on a lav faucet, because it is not so traumatic to consider the whole thing disposable. But when I put in a shower, I would like to expect 20+ years out of that, until the next major remodel.
