Purchased this faucet 9 months and had it installed by a professional plumber.  Always have purchased Delta products.  This faucet has become hard to turn off.  Will cut off only if it is pushed to the right and gently pulled down.  If handle is in center or on the left, faucet will drip or have a steady stream.  Disappointed in the quality.  First time I have ever had a problem with Delta products.  Will be expensive to have plumber come out to replace.
