Review on ⚡ Reliance Controls THP103 AmWatt Appliance Load Tester/Plug with Ammeter and Wattmeter - Blue by Tim Knoepfle

This does NOT work. I put this FAULTY tool in an outdoor drain pump. During heavy rains, I installed a sump pump in case it was pumping out more groundwater than the French drains alone. I've never seen any significant current draw that should be drawing several amps with the pump on in this review. I toggled between power and current readings but still got NO DISPLAY. I doubted the pump was working and got out manually by raising the float switch and it works and there isn't a significant amount of water left in the sump. The only test I didn't do is have someone stand by the reader while I lift the float outside. I do NOT recommend this device.
