We purchased this about 7 years ago.  It has exceeded our expectations.  It has performed extremely well.  It came with a lifetime warranty.  We needed some replacement parts after 7 years due to continual use.  When I contacted Pfizer, they promptly sent the needed parts at no charge.  We are sold that this is the only company to purchase faucets from.  They back up their finely produced products!  One of our best purchases ever!!!!
