Good value

3.0

While it's certainly not the absolute best meter on the market, it offers quite a lot for the price. Useful features are LCD backlighting and temperature measurement with the ability to switch units of measure.

The case appears to be of standard ruggedness compared to other meters in its class and the most obvious "standard" thing about it is the latency in continuity measurement. Compared to a Fluke 115, the Amprobe responsiveness is lacking which can be a problem in certain circuit probing situations.
