There is nothing I dislike about this Non-Contact Voltage tester. Works great and is very easy to use. The flashlight is a great addition helps see very clearly when using the voltage tester.

Dual Voltage tester, with flashlight, works great

Would Recommend

I own several of these by Klein Tools in a slightly different version. Needed to check for current when replacing a hot water heater, but couldn’t access the other testers. Picked this one up for convenience. It includes a dual voltage switch and a flashlight, which was useful in this instance. It worked perfectly, as expected. Plan to keep this one in a kitchen drawer for better access when my electrical tool bag is not readily available.
