  • Well worth me spending more money for this tool
There are several things that stood out to me, first was the overall quality. Nothing light-weight and cheap. The cables were heavy duty as well as the clamps and connectors. The tool felt great in my hand and the probe was thin enough to get into tight spaces but not that thin that I felt I would break off the tip. The additional cord is nice when I am working on two cars at a time in the garage. No need to swap the battery connectors back and forth. I really like the tone difference for the ground and hot. I know where I am without even checking the screen. I knew about the power up feature when I purchased this, meaning the ability to fire up a component with the second lead right on the tool. This has come in handy so many times when doing a diagnostic. A feature I did not have on my last probe which saves a lot of time not having to mess with additional cables. The screen is clear and the overall operation of the tool is simple. Just connect it and you will discover the features as you need them. I have owned Autel scanners in the past, but this is a step up. It feels more like the pricey testing equipment I used when working at the dealership. I am very happy with this and will be making sure to check this Autel brand out before my next tool purchase. ... show more

  • Money Well Spent
As an automotive repair technician, I am always in the market to work smarter and not harder. Therefore, I needed a tool that is durable and can help me diagnose vehicle faults at work. The PS100 is definitely what I needed. I can now apply power to fuel pumps, fan motors, relays and other components on a vehicle. It also came with an 20ft extension so I can get to the rear of trucks and also power up from the cigarette lighter socket. It's really simple to use but beware. It's not used for low voltage module control components. It will damage the module if use wrongly. I'm pleased with the build and I like the additional features on it so I can do quick resistance checks. It's a must buy for your tool box ... show more

  • Great tool
I purchased this since it was cheaper than the power probe brand plus the fact it comes with the extension. It also comes with a 12v outlet plug if you don’t want to hook up to the battery directly. The only thing I would have wanted with it would be the wire piercing leads. Overall great tool and probably the same thing as the power probe brand any way lol. ... show more

  • A meter with extras
Nice meter with added functionality. Power cord is plently long. Being able to apply power or ground at the tip is handy.

  • Great little addition to the toolbox
Love this, it's simple and easy and does its job. Nice that it has a carrying case. So far it's great for me not getting zapped and knowing what's got power

  • Excellent price and excellent quality…
Excellent product and works as the higher dollar brands. I used these probes for so many things. The biggest test for me is parasitic draws. This is an excellent tool for that. Voltage drops, Charging faults and lights and virtually any other electrical issue that you can think of. Service after the sale and quick shipping. Sturdy case, sharp probe end, an extension lead and battery clips. All packed nice and neat. I use in a commercial setting daily and can tell you this is a great tool! ... show more
