Extremely pleased with this beautiful faucet.  The pull down sprayer is very smooth when extended and when returning to faucet base, it glides very easily with the “DockNetik” feature, docks easily.  The sprayer is wonderful and the swivel ball joint attached to the hose makes it so nice to manipulate where you want the spray water to go. This new Kohler faucet replaced a 3 year old Delta.  The quality and ease of use, there is no comparison- much better!  I am pleased with my choice and would recommend to purchase.  Love it!!
