Nice Display

A great value! Good brightness of the digits it is small and easy to mount.


    Excellent voltage feedback

    Very clear day or night. Perfect for what I needed. Will buy more for other vehicles


      Absolute excellent quality and Superior craftsmanship

      These little guys are absolutely excellent and Superior in their quality and craftsmanship. Was made and works exactly as promised and is easy to use. Easy to read and to install. Looks absolutely cool. Was shocked over the quality of work and the excellent craftsmanship that was put into this and you can see that a lot of time was in fact put into it.


        They work well and easy to wire

        I have a prototype with a voltage regulator that uses a trimpot to adjust the voltage and because the board controls a mechanical device that vibrates, I needed to make sure that the trimpot is not changing its value overtime after multiple vibration cycles. These came very handy because all I needed to do was solder the black cable to ground and the white and red on +5V. The price is right and they are very accurate (+ - 0.01V) right out of the box when compared to readings of known calibrated digital multimeters. Yet, having the ability to calibrate them is a plus.


          Convenient and easy to use

          Easy to use, accuracy seems very good compared with multimeter voltage, easily adjustable, recommended and would buy again!


            Very cool little voltage meters!

            Used these in a small electronics project. They work great, displays are bright, and decent build quality (potting is good, mounts are good, wires and screens are delicate). good meters and I'm happy.


              Perfect size

              Perfect size for my project. Requires a little calibration, but the work great.


                Bargain, good quality

                They work great. Bought a few boxes full and have had no issues with any of them over the last few months. They come almost perfectly calibrated, but do have an adjustment screw on the rear if you need. They do work fine all the way down to just a couple of volts, and also show 3 positions at all times (whether 12.3v or 4.56v) so they are nice quality, well designed, and great for the price. Definitely buying more.


                  Bright, easy to read

                  These arrived quickly and they were what I expected. They are very bright and easy to read. I would buy them again if I need more. Which, I imagine I will in the future.
