Today I got the 210E Pro delivered from UNI-Ts official store on AliExpress. Seems to work great! mA measurements are quite precise. It's trivially possible to measure to measure the current for an LED or a relay. Or check current drawn from a microcontroller on a breadboard. Just a few mAs of error relative to my Fluke. I did some testing in devices like PCs and AV gear where boards or devices are connected with Molex connectors to a central PSU, seems to work fine. I did some testing in the 20A range by hooking up some power resistors to my bench PSU. There is a bit more drift, but it's still more accurate than the crappy ammeter in my bench PSU.
As a general DMM it's quite crappy with a slow continuity tester, a long wait time till it gets down from the MO range to measure a 100O resistor, no features like min/max, no manual selection of ranges and it's of course just 2000 counts. Of course I bought this device 99% for the <2A DC current measurement feature, so anything else is just a bonus, like having a 2nd multimeter.
Hope it keeps working, I'm quite happy with what I got for <40EUR delivered.
