I've had this unit installed for about 3 years. Within the first 10 weeks of use, hairline cracks developed on the handle around the spray toggle switch, and have grown worse over time.In addition, the faucet housing is loose on the base -- it can be easily rocked back & forth. I've tried to tighten it, and even had 2 plumbers look at it; neither were able to do more than hand-tighten it, due to an odd configuration of hot and cold water lines that suuround the washer bolt holding the faucet to the base from beneath, which prevents any conventional tool to access the bolt.Other than that, the unit works fine and is an attractive, ergonomic design.
