Review on Dmyond Digital Display Voltmeter Multimeter Measuring & Layout Tools by Juan Castillo

These are very nice little displays showing voltage and current. I've used two of these in a dual voltage AC power supply and they work great. They show 1/10 volt below my DVM, but I don't know if the discrepancy is due to the displays or my meter. In any case, they are accurate enough for my use. I recommend carefully removing the device from the case, inserting the case into the recess and then putting the device back into the case as this will make installation easier. The schematic is a bit confusing but there are many YouTube videos that make it easy to understand. I would highly recommend these small displays and will purchase more as the need arises. The goods arrived on time, well packaged and undamaged. A good thing!
