This faucet, model 7185ESRS, has been in service since 2014 and includes the plug-in powered option instead of the battery pack. During that time Moen replaced the "brain" controller under warranty even though the warranty had just expired and the cartridge was replaced once. I believe that the cartridge replacement was not necessary as I found the nut had become loose when I removed the handle. The best part about the faucet is the no touch feature to activate it as well as the dual sensors that can be individually turned off. I only use the top sensor. The Brantford has always performed flawlessly and although I prefer a simpler design, I highly recommend it.
