Review on Pressure Monitoring Backlight Wireless External by Colton Scheehl

I bought this for my motorhome. We never went anywhere for more than 30 days. Then it didn't work properly. It turns itself off and then on again. Then it started showing nothing but a blank screen. I tried working with the manufacturer but they wanted me to replace the batteries with something solar powered? There is no way to change batteries. Revain then refunded my money with no response from the company. Save money and buy something else.
