Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Pros:
Easy to use. Almost constant current consumption (9-13 mA, depending on display elements in use) over voltage range. Relative error about +/- 0.1V over range. Better than 0.4% in 8-16V range.
Cons:
An average of 10.7 mA current draw may be a bit high for some applications, but this is not based on LCD! Above 17V the meter seems to show 0.1 V too high. May not work all the way down to 3.2V. Mine works fine at 3.3!
Other:
Please disregard my previous entry. I found a major flaw in my setup!
Bottomline:
Plug'n Play, really.
