No contest, in my book these are an inexpensive, compact, absolute winner for multi-battery systems in outdoors vehicles. It's easy enough to find a spare cig lighter size mounting hole, or simply put the drill and holesaw to work in a safe space in your dash, connect 2 positives from say; your VSR, plus add common negative wire and bang, it's done! And even if you don't want to splice in a cheap inline switch for convenience, the minimal current draw of these LEDs would barely drain noticeable current even if just left always on 24/7. And few would argue that it's always nice to know how much that fridge or lighting system draws over extended time so you can avoid draining the batteries to unsafe levels.

I have brought different brand voltmeter before but this is so easy to read on all different angles and you dont have to be directly infront of the gauge to read it. Great price .

Good size easy to fit and clear display, just what I wanted. The only fault would be the pins are little close for 3 crimpets.

Great little gauge for reading both battery voltage easy installation for mounting in the engine bay no need to get out the multimeter to read primary battery voltage and second battery voltage

I really wanted a blue LED We got 2 of these voltmeters There were voltage discrepancies of up to .3 of a volt between the main and aux LED on the same unit tested on the same battery. Both units had the same amount of inaccuracy. Disappointing because I really wanted the item
