Extech Voltage Testers Editorial Review
The Extech VT30 LCD Multifunction Voltage Tester is a compact testing tool with many features. It can detect voltage to outlets covered during a remodel, current in a shielded cable, and read through wood molding where wires are hidden. One button switches between 24-1000V range, and the other one turns on the built-in flashlight. However, one major drawback is that there's no way to shut it off completely. In customer reviews, some customers claimed the device had failed after a short time. Others praised it as a good testing tool. Overall, the Extech VT30 LCD Multifunction Voltage Tester is easy to use and works well, with the only complaint being it sometimes fails soon after purchase.
