My first impression after opening and installing batteries was that this meter is very well built considering the price and manufacturer. I had read some reviews stating that it's amp measurements were not accurate below 5 amps, I haven't seen any issues in any measurements I've taken, even side by side with my fluke meters. I've successfully taken accurate amp, voltage and continuity measurements with this ETCR6920B, the display is nice and legible. I haven't tried storing data and making transfers to a PC yet, the soft case is good enough for storage on a shelf and the test leads are of good quality and rated for 1000v. There's nothing bad to say about this meter especially when you consider the price, it's a really great meter.
Works as described.
