Purchased this faucet brand new and the cold side handle won't move at all after 18 months.  Warm side handle is also getting hard to turn.  This faucet was a nightmare to put together, and was installed along with a new vanity by a professional.  Getting under there to do a repair will be dreadful, due to the design of this faucet and it's connections.  I purchased this faucet for the look and warranty.  Unfortunately, I'll have to see what the warranty is all about after only 18 short months.  I have a bad spine and can't bend or twist, so I'll have to hire someone to repair this thing.  This was my first Price Phister product, and may be my last depending on what Price tells me.
