Its 1 of those low end but decent DMM, there's a few clones like Vichy VC99, using the FS9922-DMM4 , with very little input protections
A few too many times I know I applied voltage when still resistance setting for instance. When I'm turning through the dial settings it seems to easily get stuck on the LCD and lit up the wrong things sometimes as it turns through the dial.
If it lands on the right setting, they all seem to work as far as I can tell, and to what seems the normal accuracy/readings.
I've had it apart a few times, maybe I have the dial too tight or loose/etc?
This happened back in Feb, and I've barely been using it since, so IDK. But when it works, it seems fine. But when it gets stuck changing between settings, I have to turn it off it reset it
