  • Amazing tool for the price
Style: P100
First let me be clear, if you make a living using this kind of tool, get a Snap-on or Matco or something that comes with the big huge warranty and is built beefy, but for me, I only use kind of tool every so often and for that it is perfect. First, it comes with a 40 foot cable. That is amazing! I love that part and is what initially sold me on it. When doing trailer and RV wiring I can power it by the batteries in front and I have 40 feet to mess around with. I could not find another tool with this length in this price range on Amazon. This was the best. As for functions, it has all the basic functions you need and a couple of advanced ones but it is not as advanced as some of the really good automotive ones or the Flukes but again, at this price, what do you expect. That vast majority of the work you'll be doing will be done just using the normal functions so this fits the bill perfectly. Overall this is a great buy and I have used it quite a bit across hundreds and hundreds of feet of wire and I have not had an issues with it. It is accurate, and always works so I can test the circuits. ... show more

  • Fast Diagnostic Tool
Style: P60
First Impression - Easy to use. The bright color is easy to find in my toolbox. This tool streamlines electrical troubleshooting on the fleet I maintain. This works on tractors, trucks, trailers and agricultural implements. Any 12-24v DC system I take it to. On mine the tip will heat up until it glows when you power something, so be careful how long you hold the power button. I use it momentarily with no problems. The beeps and buzzers are impossible to ignore because they are bright and loud. That makes this tool safer IMO. There is no internal battery, which makes it even safer, and simple to maintain. The wires are long enough to reach the tail lights on almost anything. I really like it. It's intuitive, fast, brightly colored, and makes me look like I know what I'm doing even when I really don't. ... show more

  • Great for DIY fixing vehicles
Style: P60
I'm more new to automotive electric so this tool definitely was perfect for me. I was able to read the instructions and diagnose my cars wiring problem in no time. The light on it is very bright so that helped me in dark cramped spaces. It functions perfect for the price.
