I've been using my new faucet for about a month.   The quality is outstanding!  The 3 spray functions are perfect,  my favorite being the strong flat spray to clear dishes.   It was easy to install,  my husband was busy and I was able to install all on my own with the inched paperwork.  I had never done any like this before, so I was impressed it was so easy.  Water flow is amazing,  and the faucet hangs far enough until the sink, so that I get way less over spray into my counter like with the old one.  Kohler products are far superior,  and we have been slowly replacing all of our new homes builder grade moen products out with kohler.  Our water pressure has improved so much in doing this,  thank you Kohler for making a superior product.
