Purchased and Installed this faucet and it worked perfectly for a few months. Then I noticed the LED indicator worked only when the water was full hot (red). Today my wife texted me stating the faucet is doing its own thing rapidly turning off and on. We installed new batteries, same thing rapidly turning off and on. I removed the batteries, removed the electronic valve effectively bypassing the touch on/off operation. We now have an extremely expensive manual faucet. We liked the faucet but it should have lasted longer than a few months...
