Good quality, works well, accurate voltage display
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.

Impressive quality
Highly recommend this test light for a several reasons. The overall quality is excellent. Doesn’t feel like it’s gonna break if I set it down too hard. The digital display on it is so much better than ordinary test lights that only have a cheap flashlight bulb in them. The Large, bold, clean cut numbers that it displays are Easy to read day or night and appear impressively fast. The cord is much longer than any I’ve used before and the clamp is bigger as well giving more options to connect to. I feel like I got way more than my money’s worth and will most definitely be buying more

Awesome in every way. A must have.well built !
This test light is great! The feel of it the build is strong. It has a nice cord and clip and a sharp point all that and a digital display with a back light. And also where the wire comes out of the top of the unit it has a nice plastic wire support to prevent kinking and over bending of the wire. Overall an awesome product that works great!! Thanks.

Very nice tester to use
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.

Easy to use and great visibility
Haven’t put this tester in a lot of use, but from first impression the tool appears to be made well. Instead of a traditional light on the handle, this provides you a voltage reading which is why I chose to buy this particular tester. This gives me not only that there is power present at what I’m testing but I can also use this as a volt meter. Great tool for the price it’s sold as.

Must have tool.
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.

great, simple effective. eaay to use
okay take 2. (ughh) 3 stars becsuse it died after 30 or 40 (or so) uses. and is cheap enough to buy 2 and be better off than with $100.00 overly complicated junk from your local supplier thay might last a dozen times after the average joe (or jill) figures out how to take a simple voltage test. that is before we calculate the excuses the retailer gives instead of a replacement or refund. loved that tester, till it quit testing..... of my several. it was my favorite (but onlu tests voltage not ohms (continuity) or diodes etc .
