Great tool for the price!
I use this all the time for quick voltage checks. It’s easy to read and accurate, and can be hooked to the positive or ground side of a circuit, red LED indicates power and green LED indicates ground.The clip could be better and because of it’s construction it is possible for the circuit board and display to rotate inside the housing when you’re trying to reposition it, but for the price this is a great voltmeter test light and I really like how the rubber cap for the probe is attached to the cord.

Small and easy to use
Cord is long enough to reach across my Chevy Silverado from battery to fuse box-Extremely easy to use, great cost for the product. It is well made- and functions well (I have yet to see a green light they’re all red, but I’m a woman who doesn’t know much lol and only uses it for fuses -). Fits right in the glove compartment and can be used at any time- works great for what we boogie it for.Would buy again !
