Small size - quite compact
Rugged - appears to have fairly thick plastic and reviews are good
Appearance - very readable with bright white background and mulitcolor display, bright orange needle
Function - quick, responsive meter movement
Adjustment - Zero adjustment for needle. Zero adjustment for ohms
Range - somewhat limited, but this IS a mini meter. You know what you are getting when you buy it. Ohms are limited to just the 1K scale. As mentioned in one other review, a lower DC scale, perhaps a 3V scale would certainly be better than a 250VDC scale. You will likely never measure a DC voltage over the 150V range (provided) but you certainly will be measuring common batteries, which may be 1.5V. You have to measure a AA battery on the 10V scale and you lose a bit of resolution here over the missing 3V scale.
Marking error - This is a goofy error that shows carelessness in the design. The scale selector switch shows 250 V scales for both DC and AC. There IS NO 250V scale on the meter face! There is 10, 50, 150, 300 on the meter face. So what scale do you use to view the so-called 250V scale. Turns out that 250V on the selector switch goes with 300 on the meter face and you probably would have guessed that but no way to know without confirming. Generally the voltage selected on the rotary switch tells the voltage for full scale deflection, but not in this case! I had to determine this by noting that setting to 250V and reading a 120VAC line displays 120 on the 300 scale. I have never seen a meter with this error. It is something I would expect to see on a Chinese Harbor Freight product. Not that this meter isn't Chinese. That's the reason we can get it for $12.
So, actually a nice little meter with generally useful scales. I'm docking a point, though for the messed up selector labeling and the fact that they could have easily put a useful 3VDC range on there instead of a 300VDC range.
In fact, I may open mine up and change the resistor go give me a modification on that range. If I do that, I'll post the hack for those interested. Hope they use through hole components and not SMD.
