Technical Review
TL;DR - Accuracy is much greater than the spec. The display is bright. The documentation is in Chinese but has been translated below. good bang for the buck.Details:the meter came boxed in a hard plastic case to protect it.See attached images so the packaging and instructions.the instructions are in Chinese but it is pretty easy to figure out.AccuracyI found it to be only 4.8mv off at 7.7000V which is 0.06234% error ratethis exceeds its spec of +/- 0.3%the test was done with a 120000 count meter that is in calibration.current requirements.I found it to pull 24ma at 7.7v I did not do current tests at other supply voltages but I did test the advertised supply range with no issues.specs:DC BidirectionalVoltmeter DC Bidirectional VoltmeterWorking voltage: DC 4~28V (5~12V recommended)Measuring range: DC -33.00~+33.000VAccuracy: +/- 0.3%Definition of lead wires:Red wire (Red): VCC~instrument working power positive poleBlack wire (Black): GND~common negative pole Yellowwire (Yellow) V++~measurement power supply positive poleLead Length:145mmProduct Size: 47.6x28.7x20mmInstallation hole: 45.2×26.0mmPackage size: 52×68×24mmproduct weight: 30g (including package)I hope you found this helpful

Excellent visibility and accuracy
The meter was exactly what I needed to complete a high power analog power supply.

There is no reference input other than ground.
So if I want to measure the output of a sensor with this meter that is remotely located, there is no way to easily eliminate the voltage drop across the ground wire to the sensor. Fortunately it was below a threshold that made it barely OK. Otherwise works great.

Seems to be very accurate
Accurate and easy to view.

works good update but has now quit
didn't need the numbers to the right of the decimal point so I covered them up with electricians tape.01-27-2025 The volt meter has quit!! The numbers are all over the place. The decimal point moves around.Ordering from another manufacture hoping It will last

Yes a low cost precision meter
A much more accurate display of battery voltage. Three decimal places is very useful in tracking the visual change rate between 13.2 and 13.0 volts
