Review on 🔌 Auroland Non-Contact Voltage Tester - Adjustable Sensitivity Circuit Tester with LCD, LED Flashlight, Alarm - Detects Range 12V-1000V, Live/Null Wire Judgment AC1 by Brandon Hunter

I already have at least five normal voltage testers, ie. switches on and off, but often deceives, ie or vice versa. I found this model with sensitivity adjustment almost by accident and I have to say it's another planet because even with wires in the wall you can understand a lot depending on the depth of the pipes. Knowing if there is voltage without touching wires or objects is really very important to understand if there are crowds without risking lives and this product helps a lot. The price is very affordable as it includes shipping for first time buyers.
