Good quality, heavy built
Only used it once but it is a heavy built and easy to use. Better than the cheap test lights I heavy and a good value for the money.

Looks to be pretty well made. I like the length of the cord. Appears to be well made for the money.

Professional Quality
I bought this tester because I wanted to know a little more about my quick circuit testing than a dummy test light will tell you. This thing checks all the boxes of high quality. I have been using it on 36 volt and 48 volt golf carts. Helps in checking the batteries and running your lower 12 volt accessories without burning them out. I have used a lot of different testers over the years and this one hands down is better than any other I have ever used. It is my go to tool. I use this every day and it is far easier and quicker then getting out my $200 meter (that is a pain in the butt to use). The only negative is that the meter does not give any measurement past 48 volts. However, LOL. I did buy this as a 3v-48v tester and it does that job precisely. Great customer service as well if you have any questions or issues with your circuit tester.

Good quality and easy to use
Bought this after i fried my regular test light-didn't know it was for 12 to 24 volts. I used this for installing some battery gauges on my golf car-48 volts. It works great. Easy to see the numbers on the tester even after dark. I really like the way it's lights up so it's easy to read after dark. the ground lead is plenty long with a good clamp on it. I defiantly recommended this tester.

really easy to use and the spring cord keeps everything neat when your work and the lights on the display helps to see thing better in dark spaces like a fuse box
