Really nice

Really nice. Finally something I can understand and how to use without having to figure out when or which knob to turn where or what button to push where. This does it all for you right out of the box.

Simple and easy to use

As a homeowner who needs something simple, this is perfect for me. Used it a couple of times on my RV and house. Love that it automatically detects so I don't have to worry about the dial.
