Review on 💡 bayite AC 80-260V Digital Power Energy Analyzer with Current Voltage Meter and Open-Close Split Core CT by Oso Mears

The description states that the device saves data when the power is switched off. I had this plugged in for three days, yesterday evening the power went out, when the power came back, the device did NOT keep the measured consumption of the first three days of operation. The button to delete data was NOT PRESSED, so don't even think about blaming me for it. This device simply did not perform its advertised function. The device readings for a purely resistive load are approx. 10% higher. The split-core current sensor, as mentioned in some other reviews, requires careful handling and triple checking. After installation, the latch is correctly engaged.
