Good quality, would purchase again.
Very pleased with the price and quality.
Volt Meter works fine and seems to be quite accurate. It should be noted that the LED power draw come from the MAIN source only and I measured it at 16ma while the AUX current draw seems to be only leakage current which I measured at 123 microamps. So I connected the MAIN to a keyed source and the AUX directly to the second battery. (123 microamps is so small that the effect on the second battery is negligible.)
Easy to install and works great 👍
