After 15 months of use, the unit failed. The screen backlights, but no read outs on the display (see pic). I shut off power and re-energized in the unit, checked wiring at battery and at unit...all secure. Battery is at full charge according to separate voltmeter, and devices in my RV where unit is installed. RV is in heated garage. I have to assume it's an internal device failure. Disappointing, as I had high hopes that this meter would last for at least a few years. I caution those considering purchasing this item.
