      Color: NeonVerified Purchase
      This spark plug tester did work out of the box. It was a bit difficult to see the spark light in the garage during daylight hours. I had to close the garage doors so I could see it. Once I got it out of the natural sunlight (it was quite dark) I was able to see the spark indication light. The cable is also quite short so you can't move it to be able to see it while pulling the start cord. works better with 2 people. It was very cheap and it did work...4 stars.
