I bought a $400kitchen sink faucet as part of remodeling my kitchen. After only 4 years the faucet is only providing drops of water. I contacted Kohler. After 3 weeks waiting for a "valve" that I'm supposed to install, the valve hasn't even been sent! I have tried and tried to convince a customer support agent to help me but they just don't care. I will NEVER buy another Kohler product. They have serious quality issues and won't help. AVOID KOHLER!
