UT210E
SPECIFICATION
Alternate Current 2A/20A/100A ±(2.5%+5)
Direct Current 2A/20A/100A ±(2.5%+3)
Alternate Voltage 2V/20V/200V/600V ±(1%+3)
Direct Voltage ±(0.7%+3)
Resistance 200Ω/2kΩ/20kΩ/200kΩ/2MΩ/20MΩ ±(1%+2)
Capacity 2nF/20nF/200nF/2μF/20μF/200μF/2mF/20mF ±(4%+5)
So the low current range is slightly worse accuracy (+0.5%), but has much wider range (0-6A). AC current and voltage have the same stated accuracy.
Not sure what you mean by range button, UT210E doesn't have it right? But this thing does not have manual ranges, so auto range which is good right.
Its cheaper on Aliexpress as well:
