Real tool for real work
Was tired of Harbor Freight drop it once, and throw it out. This is the real tool for real work.

Great quality
Very durable. I like straight cords better than stretchy as they are stronger and don’t get caught on things. Very well made. Rubber sheath wore off after much use. Just replace with a piece of heat shrink if it does come off. Clamp is heavy duty. Great quality.

Work great two thumbs up
Works great no more pulling fuses and guessing if the fuse is good and great for all 12volt electrical

Best Test Light out there by far!
Best test light out there. Use it from simple light testing up to circuit response testing 5V sensors. Love the feel of it, definitely quality. This tool paired with a good Multi Meter can take on anything.

Decent product for the price
Nice test light, the light could be brighter and the ground connection is poor quality.

Identical to the heavy duty one off the tool truck
Same heavy duty tester that cornwell offers or at least the one I've bought off the truck

Current draw
At 14.5 battery voltage it was drawing around 150-160 mA (.150 of an amp)

Heavy duty make. Long thick flexible cord.
Feels sturdy in hand. Cable is higher quality. Definitely would buy again.

It's a very nice test light
Very nice and well made test light. The cable is high quality, the kind that stays flexable in very cold weather.
