I had a kitchen faucet I liked the look of but the handle never moved smoothly after many cartridge replacements. My plumber recommended Koehler. I called the company and a very nice young lady helped look through all the single lever faucets that would work on my sink/ counter situation. I decided on the Bellera single lever semi professional faucet. It looks beautiful and I love it! The handle moves so smoothly and the magnetic docking and sprayer work great! Wish I had changed out sooner.
