Any using the ARP RV Fridge Protection Device?

I ordered and received on a couple weeks ago, but haven't installed it yet. We tow a lot in the mountains, and often find ourselves parked on overlooks etc that are far from level. Figure once I install the ARP I won't necessarily have to hop in the 5er and shut off the refrigerator every time I'm off level. I've never had any issues in over 30 years of off again on again rv ownership, but always worried about the fridge.

I got the version with a fan controller and two fans since my fridge is in the side. It already has a fan, but didn't work all that good till I modified the fridge compartment to channel the hot air towards the top vent with a sloped deflector.
