Kohler has amazed us with customer service and quality products. We ended up returning this one for the non-semi-professional version of this, because we realized that we did need a hose for our large sink with deep corners. The goose neck on this faucet, we didn't realize, is not flexible and so the faucet spray couldn't reach all the way to the edges of the sink. We were careful during unboxing and installation and didn't run water through it, so that made the return simple and easy. We are SUPER happy with the other similar model in the Crue faucet family.
