As described, works as it should. We use bottled water for consumption as we have hard water here. My fridge has dual ice makers in it and requires 50 psi to be able to feed the water cooler function and ice makers.This solved the issue. It's automatic and kicks on and off when it needs to, works as it should, overall good product and happy so far at 2 months in to service. Would buy again and would recommend it. Slightly loud but it only kicks on for a few seconds here and there and that would be just the way I have it mounted. Its in a cabinet next to the refrigerator so I could hide the water bottle. I'm sure if it was a more solid mounting area it would be far.less noticeable.
