Every part of this product is substantial, much more so than the standard issue. We have a large, deep sink, and our previous faucet (about the same size) was limited by its' fixed linking arm when you pulled the hose out to spray down the sink or rinse a large pan --- the Delta is MUCH more usable. In addition, the previous faucet sprang a slow leak from its black pull-out hose after only 6 years of use --- down the back of the cabinet and wicking under the floor, necessitating replacing and refinishing part of the kitchen floor. It also had a "Lifetime Warranty" guarantee; but when I examined the fine print it says "this warranty applies to the finish only". Read the Delta warranty and you'll see there is no comparison. We just had our new bathroom done with all Delta fittings, and every plumber with whom we spoke likes the Delta quality.
