Review on 🔌 Sperry Instruments STK001 Non-Contact Voltage Tester (VD6504) + GFCI Outlet / Receptacle Tester (GFI6302) Kit, Electrical AC Voltage Detector - Yellow & Black by Motogp Portillo

Today I tested both devices. Socket tester met my expectations. The non-contact voltage sensor did not meet my expectations. After some random testing, I concluded that the proximity sensor is likely detecting the presence of voltage. However, it seems to send a false positive signal to almost anything metallic. A watermelon and a screwdriver squeaked for me. How can I trust that to tell me something's wrong when fresh food creates a signal?
