Super. Didn't install yet. Checked sensor. Sens distance good. Off delay about 1 second. Power supply also works from 120 volt. Valve doesn't spend power for keep it opened, so battery should last long time (if used). On other hand if you cut power during washing, then it will newer stop until you power it up again. So maybe to put battery together with AC power is good idea. I'll add comment when connect to the water.
Quality automated tap and relatively easy to install too. Hot/Cold temperature is fully adjustable. Very happy with the product. Hopefully the cartridge will last a long time.
