Super nice multimeter..
compared with Fluke 87V , Fluke 87, Fluke 287, Fluke 289, Fluke 867b, 187, 189, Metrix, Keysight, Brymen... (i compared only with high level handheld multimeters)
This multimeter is absolutely accurate. Nice features like low burden measurement, bluetooth, sd card (i like it for fw upgrade), crisply lcd display and build quality is just awesome.
I'm sure Dave will improve the SW side.
I compared specially Fluke 189/289 vs 121GW, they have similar specs. (I used ir3000FC bluetooth adapter on fluke's)
121GW software (android) is better
121GW has more features
integrated bluetooth
same accuracy
open source
and you can buy 4 121GW instead one fluke..
Thank you Dave ! specially for the color
