Bright and easily readable. Blue display. Needs about 4 volts to operate. Connect the red wire to plus, black to minus, and the third one to the source you with to measure. I will built this voltmeter into my DC power source which I use in my amateur electronic workshop.
Could use a manual, at least power voltage could have been stated. Not a con really, just a minor gripe.
At $4.3 this item is a bargain. I don't know how accurate it is, but at that price who can complain?
A must have for any self-respecting amateur electronics builder.
