Review on 📊 DROK 90538 Flat Plug AC Voltage Panel Power Line Test Monitor Gauge Meter - 110V 220V LCD Voltmeter by Jared Gopalan

I like to measure. I want to know the temperature of my fridge, the humidity in the room, the WiFi signal strength. I never *need* a volt meter, but sometimes I need to check my work outlet is working, so I have this little guy. Just a week after receiving it, some of the electronics in my house started behaving strangely. The wired smoke detector worked, there was no smoke. My microwave showed a cryptic error code on the screen. Since it was a hot summer day and I suspected an electrical problem, I decided to use my meter to check the voltage and found that my whole apartment was less than 100 volts! I immediately turned off all my electronics and waited for the power to restore to 115 volts to avoid damaging my expensive equipment. Thank you for developing this simple and effective product. Every home should have one.
