I've had this faucet for about 4 years.  It works great.....except.....it has a plastic insert in the gooseneck that is the catch for the nozzle head.  This thing wears out after 2 or 3 months.  To replace it, you have to turn off both supply valves and crawl under the sink, lie on your back and depress a very tricky and hard-to-depress ring at the very top of the hose connection.  Then, you crawl back out, pull the nozzle and hose out and only then can you replace the plastic insert.  I've done this about a dozen times.  IT SHOULD HAVE BEEN A MAGNETIC CATCH, like everybody else's.
