    I tested this small Volmeter with respect to my full scale one.
    It was accurate and very easy to use.
    I intend to put it on a DIY power supply from an ATX PS, to be used as a lab PS.

    full working , in full scale range 😀

  3. medvonok (verified owner)

    It’s small, efficient and easy to watch. Pay attention to wires that are more rigid and can peel off.

  4. reedv (verified owner)

    This little volt meter is great! It’s small, easy to connect, accurate, and very inexpensive. I have several and put them anywhere I need to know the voltage. This is a fine little sensor.

  5. Sandman333 (verified owner)

    I add these to most of my projects, it’s great to know at a glance how well a battery or power supply is doing.
