Works
Bought this to do some troubleshooting on my Honda ATV. It worked as it should and helped me resolve my issue.

Good Product
I've seen and bought those really cheap ones in auto parts stores, and I was kind of expecting this to be the same - thin wire, cheap construction, and so on. But what I got surprised me. Pleasantly. This is a nice sturdy little tester. It will very likely last me years.

Nice product!
I bought this to test the defrost lines on my car. Sadly they are destroyed. But all the fuses are fine! Worked really well and lit properly. No issues.

So simple to use and read!
Back in the day, a tester like this lit up when you have power and didn't light up when you didn't. It is so nice to see the actual voltage to a tenth of a volt instantly. You no longer need to bring out your volt meter to do a quick simple test. The volt meter with alligator clips. Just connect the built in alligator clip and you are ready to go.
