I bought this style faucet due to my standard pull down sprayer hose fraying on my existing one.  I decided to buy Vigo due to the excellent reviews from many satisfied customers.  And....I wasn't disappointed.  Actually, surprised at the excellent attention to detail in so many areas.  From the shipping box to the operational features and the metals used that comprised this unit, all were top-of-the-line.  The ease in which each feature functions scores an A+.  Even the installation had been 
thought out carefully.  You can tell the team that engineered this worked on the basis of "if it was mine, how would I want it".  I would recommend this to anyone.
Nailed it.
