Works Fine - Accurate
These are very nice digital voltage displays. The quality is good, but I have added some adhesive to make sure the wires stay connected during handling. That's my only complaint. Some of the wires are stripped a little too much and a little tug might disconnect them, or they might just fail mechanically due to bending during handling. That was not a deal breaker for me as they are inexpensive, not cheap (inexpensive relates to price, cheap relates to quality). When I need more, I'll be back.

Cool
Cool to use to know what going on with ur battery

Beware of power-on clear!
Wanted a voltage monitor for a 9.6 V older Makita charger to monitor charging voltage and final cell voltage. Discovered this unit does not tolerate a source of high current until completely initialized. If wired directly across the battery terminals it will eventually destroy itself. Works for a short time, battery plugging and unplugging, but soon conks out, sometimes with smoke. Not knowing the input impedance for current-limiting on the red & black wires, my solution was to place a 100 ohm resistor in series with the white lead and 200 Mfd of tantalum cap from there to Gnd. (black) Crude, but seems to work in delaying power clear long enough for everything to settle down.. Too bad I had to burn 3 devices finding this out.

These work fine and are simple to use
but the wiring connection is a little iffy. you may want to dabble some hot-melt glue over the connections for mechanical support and short-protection.

Decent accuracy but low quality
The voltage meter seems to be within about +/- .3V from my multimeter so pleased with the accuracy and the 3 wires. The quality is very low so expect to resolder all those pads and replace all the wires. Other than that, the voltmeter works. The size is perfect and small as described. The brightness of the display is what I would expect. Design seems great with accuracy within a tolerance but it's quality is pretty low and ill expect some accident breakages.

Pretty accurate for the price
Pretty accurate for the price. Excellent for bench instruments.

they do not handle more than 12 volts
these are 12 volts, no more

They all work. Accuracy between the 5 units was about +/- 0.30 volts, which would be nice if it could be adjusted on the unit itself. Units will suit my needs as they are.
