Pros & Cons
Pros
One thing to notice is i had to calibrate one of the packs. Once you calibrate them they read perfectly.
These little voltage readouts are a great addition to any power supply or solar project. Perfect for monitoring the battery voltage of antique motorcycles. Easy to wire and a nice readout for the price point.
Very bright (adjustable) and fast-responding. Even in daylight the blue display is bright and easy to read.
The fluke meter measures voltage under 1 volt more accurate than the 0-100v meters. It has an ajustment pot for zero in it necessary, but non was required. If you don't need to measure < 3v than the simple two wire connection is all you need.
Cons
After turning the connected equipment off then on for the third or fourth time (i only run the monitored equipment during daytime hours), two of these digital readout smoked then quit.
Highlights
Quality
I did have to calibrate 2 of them but very easy with the pot on the back
The product arrived in a timely fashion and was well packaged for the journey
The wires come our from between the display and the circuit board so the board will not fit flush with the case when mounted from inside
Some inconsistencies in the build quality but nothing glaringly bad
Packaging/appearance
Item as described works as expected good packaging looks pretty good
Accuracy was very good on all 5 right out of the box
Competitiveness
I used one for monitoring the output voltage on a 12vdc power supply
Small compact will work great on a pc board
