I just got 4 of these little gems! They are very bright, and will measure down to about 2.5V, with the display getting very dim at that point. The auto-range function from 9.99v to 10.0v is nice, but apparently only truncates the last digit, not rounding. You see 10.0v until you are between 10.1 and 10.19v, where it will show 10.1 Still, this is a minor thing. These are great little modules, and will find their way into various power supply projects, homebrew battery testers, etc.
