Dometic CFX Portable Refrigerator/Freezer Wireless Display

Doesn't have little up digits as shown, cheap LCD display, not lit up, bad range no more than 10 feet.

I want to start by saying I really wanted to like this wireless display and that it may work better for others in different applications but for me it hasn't worked out so well. I've used it for a few months now. I have my Dometic fridge in a lockable toolbox in the bed of my truck and apparently the fridge doesn't put out a strong enough signal for this display to pick up even at 1' away. I was hoping to mount the display on the dash to see it better but ended up using the suction cup to mount to the back window. It will go through a set of batteries in a matter of a week or two so I recommend using the power cord if you can. They advertise wireless range to 49'. I doubt it even in free open air space, my test got about 20' out before I lost signal (open air). Any obstructions will knock that down quickly. The price is about what I would expect for such a gadget but I did expect a bit better performance. I even contacted Dometic about the issue thinking it was the display, they sent me a new display with no questions and it did the same thing. My guess is the US version has FCC wireless signal strength limitations placed on it but that's me speculating.
