Darryl: All five worked right out of the pack. Nice.
All were accurate. 5 different colors. Nice.
I always hot-glue the soldered connections where the wires meet the LED. That way the connections don't break - like they are prone to.
I'm very happy with these.

Matt: The 2 that I have installed needed tweaking on the pot to match multimeter reading.
Across a range from 0-12Vdc it was within .1V of my multimeter consistently once tuned.

Kenneth Graham: One big plus with these are they can be calibrated. The downside for me was the minimum voltage would not go down to 2.5v as in the description. I was going to use them to monitor the voltage of 18650 cells in a project I'm doing. 8 of the 10 would only go down to 2.8v the the leds go out. The other 2 went down to 2.7v. I checked them with a lab power supply and a 20k count multimeter. I really needed to see the 2.5v reading. Otherwise works good.

muffslayer: I love them, high quality and dense to hold! However, One of the lines on the LCD’s had a burnt out upon arrival. Other than that, i would consider purchasing again!

(Original review follows)
I'm planning to add these red and green displays to a couple of interface boxes I'm building that powers some IP cameras. I have a mix of 5VDC and 12VDC cameras I'm using so I needed something that would cover this voltage range. One box I have has 12V going in and a couple of USB ports as output. Another box is also connected to a 12V power supply but one output is a constant 12V (powers a WiFi bridge), while the other output is on a time delay which gets power 7 seconds after the bridge does. It would be nice to see what the voltages are going to the cameras, rather than use an LED which would light up as long as there's 3V or so.
I connected them to power from a USB port and calibrated each one to match what my voltmeter said (5.05V). There were only a couple of them that initially displayed around 4.90V...
