Bought this faucet 3 1/2 years ago as a treat for my kitchen.  Thought it would be great to have the water turn on without physical contact.  Today were replacing this expensive treat faucet.  The handle keeps coming loose, so irritating and its very hard to access to tighten.  Also the pull down hose squirts water all over as it has worn out!  Starting to look shoddy too, bronze faucet.  We are replacing it with another Moen though, but a less smart model.  I hope for better use and wear.
