[UPDATE]
The manufacturer seemed to have addressed the issues in this review. The solder joints are much more uniform and clean, all modules look the same (apart from color), and the bags now have a little color marker to show you which module is which. Helpful. You''ll still have to tune them to the right voltage range, though it should be easy with a tiny Phillips screwdriver.

[Old Review]>
Pros: Affordable, easy to use, bright, adjustable, great addition to a DIY project.

Cons: I received two that their ICs were soldered incorrectly. I thought they were defective, but after looking at them closely I noticed that there were a few shorts. I resoldered them and they worked fine.. aside from being incorrect. Unfortunately, these don''t come factory tuned, so the voltage was off. Luckily they come with an adjustment screw on the back to calibrate it better.

I would suggest hooking up a multimeter near by and matching the voltage on the meter with the voltage on the LCD.

WTF?

You may notice PCB has only two wires. This is because the third solder terminal has been hand soldered to second terminal. Original design includes three solder terminals; +Vpwr, Signal, and GND. However someone decided it would be a ''bad'' idea and connect +Vpwr and Signal together. This may seem like an OK idea at first, however this configuration means current required to power unit is drawn directly from circuit you wish to monitor. This is OK if you are monitoring voltage from low impedance source, like battery or power supply. But any high impedance source like circuitry or sensor output will not work. Remove hand-soldered jumper and wire unit with three-wire interface like original design intended. Other then this royal FU, unit operates fine. BTY, design includes miniature microcontroller using ADC input for analog sense, and drives LED segments with digital I/O. Rather interesting simple hardware approach. Colors are very vibrant and bright. Accuracy in nothing to write home about, but who cares about 30mV when monitoring a vehicle battery.

I asked the question "What current do these draw for each color?" In my latest project, I will be running off of (2) 9 volt batteries in series, hence 18v. I wanted to know which voltmeter drew the least current, so my batteries will last the longest. The winner was (surprisingly!) the white color. Here are the numbers:

Yellow 17.33 mA at 18v.
Red 14.09 mA at 18v.
Green 12.51 mA at 18v.
Blue 9.43 mA at 18v.
White 6.90mA at 18v.

I thought the white color was made by using multiple (RGB) LEDs, thinking that draws more current, but this is clearly not the case.

I only had my limited samples from just the one order of (5) colors to measure, so ''your mileage may vary.''

And I''d love to hear from anyone else making measurements like this to see if you also find that the white display is the most efficient.

I''ve found these a bit tricky to work into various designs because of the tiny mounting screw size and the need for a rectangular hole to see the display through. I''ve tried a nibbler tool and a Dremel moto tool but my rectangles never come out quite right. So maybe the manufacturers will come out with a similarly small-sized and efficient display in a round case? Or maybe someone out there has a great way to cut nicely sized rectangular holes in a sheet metal box?

I purchased these for a project that benefited from a dedicated battery board, and these were the perfect fit to be able to monitor voltage without having to break out a multimeter.
They are accurate enough for what I needed them for, and considering the price, I would consider them a good deal.
There were a few times where my multimeter read 3.7v, and these read 3.8v, or vice versa, but I can''t say for sure which one was off. It also didn''t matter as I did not need high precision, and while there was a small discrepancy, they were reliable in their readings.
If you do need an extremely precise measurement, then these aren''t the best choice, but they also aren''t intended as such and you probably wouldn''t be considering these for such use anyway.
For me, they worked as described, gave me a reading that was well within my needs, were cheap for a bunch of them, and came quick. I would recommend them for simple projects and kits and would buy them again.

These things are great to toss wherever you need to monitor voltage. The two wire ones aren''t quite as accurate but they''re simple to hook up without powering separately. Mine were all off a few tenths of a volt but easily adjusted to match my volt meter. The set screw is VERY touchy so it takes a little twiddling to get it right. For me, 13.5 vs 13.6 is not a big deal. If you need higher accuracy, these are not for you.

If you need to monitor voltages above 5V, these are great. Very bright, and look reasonably accurate to within 0.1V. Anything less though, they''re a no-go.
