Review on 🔌 Twidec/Voltage Tester Pen Non-Contact with LED Flashlight + GFCI Outlet Tester Power Socket: Find Breakers and Detect Voltage with TA100+TA106B" by John Clarey

Absolutely perfect product. A voltage tester is SO EASY to use to test for accurate voltage (rather than just having a dim light to give you a general idea of performance). With this product, you just plug in a regular outlet, you get bright and highly visible lights even in sunlight, and you'll know if it's 119v or 120v or whatever. If you're an inspector or homeowner, you'll love this quick and easy way to check voltage, ground, and GFCI connections. The pen is an added bonus.
