I did a lot of research before purchasing and it was evident from the moment I opened the box that this was a very high quality faucet. This was a superior product compared to the Kohler it replaced. I considered Moen and Delta but the many reviews I read convinced me to try Kräus, a brand I had never heard of. The instructions were straightforward and the faucet installed without any issues. The pull down nozzle works smoothly as does the button to toggle between spray and normal faucet. I really like the design and the smooth lines. I hope it remains reliable for many years, if so I'll be a Kräus customer for life.
