    I purchased 6 pcs, 2 green, 2 red and 2 blue. the precision of the measured voltage is OK, anyway there is a small trim on the back that can be used for adjusting the measuring precision. suggeted good value for money ho acquistato 2 voltmetri rossi, 2 verdi e 2 blu. la precisione della misura è abbastanza buona, in ogni caso c'è un piccolo tirm sul circuito che può essere ustao per regolare la misurazione. soddisfatto e suggerito, buon rapporto qualità prezzo.

    I ordered this green version and the item that I received is very bright and small as promised. It is very easy to use, unfortunately compared with my multimeter it is not very accurate in measurement, particularly in the low range where I am more interested. As you can view from the photo the units are different from the item shown on the website and didn't have the trim for the reading adjustment. I inform Banggood and they are investigating about. If you need a very small voltmeter for a basic

    the accuracy is very good and it is adjustable if necessary. The automatic decimal point of the 3-digit-display is changing from 0.00/9.99 to 10.0/32.0 Volt. I tested the blue one: It is extremely bright. A data sheet would be fine, but you can get many details from the banggod website. The power supply voltage (>3 Volt) is allowed to be lower than the measured voltage (<32 Volts).

    I put two of these on the new power supply (7A24) that I just received to power my home built golf ball logo printing machine. The power supply works perfectly and I was even able to adjust the 5V supply to perfectly match the servo motor. The 12V supply drives the two NEMA 17 steppers with no problems. It's great to be able to monitor the voltages in real time.

    J'ai reçu ces 3 mini voltmètres dans des emballages antistatiques individuels visibles sur la photo. Celui que j'ai essayé rapidement est précis. Un potentiomètre au dos de l'appareil permet de le régler. Je suis satisfait et je recommande ce produit sans hésitation.

    It displays digits as low as 3.35 volts as is being powered. The LED brightness increases with the power supply voltage.

    Das digitale LED Voltmeter ist sehr klein. Passt in jede noch so kleine Ecke. die Leuchtkraft ist sehr stark. Der Einbau selbst für Laien kinderleicht.

    fa il suo lavoro, ma mi aspettavo fosse più grande. Ottimo in un laboratorio
