Available ranges (V1.3 & V1.6):
V DC AC auto: ≈0.500--9.999V, 99.99V, 999.9V. (No manual DC AC selection. Doesn't measure voltages below ≈0.5V❗)
A DC AC auto: 9999mA. (No manual DC AC selection. Low accuracy below 20mA) 👎
R auto: 999.9Ω, 9.999kΩ, 99.99kΩ, 999.9kΩ, 9.999MΩ, 99.99MΩ.
Multimeter automatically selects one of the above measurement functions❗ 👎
.
R semi auto: 999.9Ω.
C semi auto: 9.999nF, 99.99nF, 999.9nF, 9.999µF, 99.99µF, 999.9µF, 9.999mF, 99.99mF.
D: 2.999V. (Independent of battery voltage, built-in charge pump) 👍
V DC AC semi auto:
-V1.3: 599.9mV.
-V1.6: 99.99mV, 999.9mV.

Current consumption:
-V1.3: ≈2-3mA. 👍
-V1.6: ≈3-5mA. 👍
-Backlight: additional ≈7-12mA, depends on battery voltage.
Low battery level: 2.4V.

V1.6 hidden function, can be switched to 0-100MΩ auto ranging ohmmeter only, without buzzer and constant relay switching. Go to semi auto R, short the probes, long press SEL button. 👍

Price: $8 on promotion, $12 normal.

Downsides:
Version 1.3 has a bug/bad design. For 1 sec an internal impedance of the voltmeter is about 2kΩ (PTC and 2 BJTs input protection of the ohmmeter circuitry)❗👎 This version is more popular right now. 2:02
Both have a problem with redundant switching of the bistable relay, even if it is already in the correct position.
You can't measure voltages below ≈500mV and above 599mV/999mV on the same measurement function❗ 👎
You have to use auto mode for voltages above 0.6V/1V and for resistances above 1kΩ❗ 👎
No MOVs input protection and any metal film shielding. But that's normal at this price range.

Meters would be OK without that pointless auto mode, or at least with the possibility of not being forced to use it.
