Friends, could you help me analyze which model of multimeter is more practical?

I probably have one of the cheapest multimeters at $5, and it's enough for me. Where are you planning to use it and what measurements will you take?
My model is the XL830L, which costs $4-5 on AliExpress.
used to test my hash board
To check the control voltages on the board and the resistance in a section of the circuit, a regular $5 multimeter is all you need. That's why I have this multimeter. Other testers are used to test the chips on the board.
This one can also be used to test voltage and resistance! Besides, after listening to your analysis, I bought it. It’s practical. I only have this one multimeter, and it’s pretty easy to use.
You did the right thing. If this device isn't enough for you, buy a more expensive one.
Technicians typically measure test voltages and resistance in a section of the circuit. There are no repair instructions for most devices, so repairs are generally based on the experience of their colleagues.
