    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Does nothing more, nothing less than what the description says. I connected this to an 12v battery using a switch. The display is very bright, so it is very readable in direct summer sunlight. I have it now for two years and its still functional. Once a hol...
    Cons:
    None really. Be carefull when installing, the back of the unit is unprotected

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Easy to install. Just two wires to solder and easy panel mounting. The bevel is great to hide the edges of the hole in your panel. I use it to monitor the battery voltage in my car.
    Cons:
    None really. Its just really straightforward. My expensive multimeter does give a slghtly lower voltage reading, but the differ...

    Easy to use instrument

    posted by Markymarker on 09/08/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Easy to connect, read and understand. Seems to be accurate as well: Compared to readings from Fluke's multimeter. Casing is small and can be mounted easily. Quality of electronics look ok and may last for a long time before anything breaks.
    Cons:
    None so far... maby the fact that I had to solder wires to longer pieces.

    Good voltmeter for motorcycles

    posted by adityabhelke on 08/19/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    The meter is quite compact. The digits are easy to read in daylight. The self power consumption is not much. The voltage display is fairly accurate.. Wish there was a way to adjust against a reference.
    Cons:
    The meter has no weather sealing, ie its open at the bottom and sides. So installing on a motorcycle will need some weather pro...

    Its working

    posted by mitrich80 on 04/18/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    Very simple and quality product. You only need to connect two wires to a power source and make a hole for installation. The device measures accurately, but with a slight delay.
    Cons:
    Not really negative, but my device with blue numerals and not with the red. The brightness of numbers could be more intense.

    Small and precise, this device is able to measure with clarity and precision voltages of 3.2 to 30volts. Acrylic has finished on the sides allowing fix it at the source or even an appliance testing in electronic or electric vehicles.
    Cons:
    Nothing against the product delivers what it promises and I am satisfied with the purchase.
