Review on Borbede 168A Mini Portable Digital Multimeter: Accurate DC AC Voltage Current Capacitance Resistance Testing with NCV & True RMS Diode Tester by Joseph Campos

It seems to measure about every two seconds so if you're in a hurry you can get wrong readings. But otherwise it seems to work quite well. It also had a quality issue - the battery posts didn't have enough voltage to make contact with the battery, so I had to bend them to get the unit to turn on right out of the box. UPDATE: after a month of brief use. , resistance measurements were far away. It shows 6 MΩ even if no probes are connected (see photo). Each resistance measurement is like 6 MΩ in parallel. This is fundamentally unsuitable.
