Versatile circuit testing tool impresses!

My analysis of this 4-way circuit tester revealed a product that is not only easy to use but also offers multiple testing options with its bright LED lights. It comfortably fits in the hand, and its robust build is a plus. The blade is just the perfect size to fit in different electrical systems. However, the product's side prongs may be challenging to use in some tight spaces.

Pros
  • Versatile testing options with bright LED lights
Cons
  • Side prongs may be challenging to use in tight spaces

works great without any problems

all lights work if you want to know what voltage is present at the trailer for electrical stops you have to connect a voltmeter instead of this device, it only lights up when there is electricity at the plug.

Cons
  • expensive

Designed by idiots good for power tools

I'm sure it works but when I'm plugged into my F150 all the lights look down and you can't read them. It only connects in one direction, the other side with four pins has the same problem.

Cons
  • too dumb
