A really well built test light . Its nice to have a built in voltage reading, but i was really tired of the cheap test lights always breaking . This one has a nice heavy clip and tough cord .

I bought this tester a few months ago and have used it on many occasions.I do enjoy the extra length of the wire lead and the strength and connectivity of the clamp attached at the end of the lead.The probe is very sharp and the LCD screen is easy to read.I did compare with my multi-meter and the accuracy is "spot-on".If I had to make a recommendation in the design - it would be nice if it had some kind of illumination upon a live circuit.This tester is for DC current only with a max voltage of 48 volts.Overall-I do recommend this tester for use with automotive or other areas of testing DC current.

Used to trace a loose/disconnected ground on my Range Rover, which has been extremely elusive up till now! This light tester worked exactly as described, seems to be good quality overall, and was easy to use. The cord is long enough to get pretty much anywhere I'd need it, but coils up well so it's not just in the way. I compared the voltage display across the battery terminals and across a couple of circuit points to what my multimeter was showing, and it was exactly the same. Overall very pleased with this purchase, especially for the price.

This is perfect for my job, all I need to use it is a common ground, regardless if it is 12v or 24v.

I use the tester to check wiring for bad connections and faulty grounds in automobiles. It does the job as intended, plus it shows the actual voltage present at the connection point. Plus, I use the tester with CCTV security systems, as most systems are based on 12 volts DC and some are 5 volts DC. The unit's size is larger than the cheaper and smaller lighted continuity testers. A good value for a useful tester for your tool box.

If you're like me and try to repair anything to save money, this tool is a must. I frequently use for checking fuses in vehicles. Great for checking draining battery issues. While care is off, you can check for power drain and find what system is malfunctioning.
