Impressive
Since I've only had it a few days, I test tried in on my own vehicles. I have to say that after setting it up and doing only the updates I require, it instantly located my vin and all the modules. It found issues that I already knew I had, but in total detail. Pointed me in the riggt direction so far.
Its quick and holds a charge well and I like that it has the wireless setup. I can move about with the tool and see exactly what's being registered on the display.
I like the overall look and feel of the unit itself. It powers up fast and prompts are especially helpful. Its definitely more powerful and you get more out of it than just a basic run of the mill code checker. Obviously its worth the money ive spent for my needs
I am new to this end of the spectrum on analyzing all these new computer gadgets found in sonmany cars now but I definitely needed this to advance on better diagnosing deeper issues down the road.
My only negative feedback is the actual case it comes in. I would like it better if it was a hard case with actual foam cutouts for all the equipment. But I'll make due fir now. It is rather difficult sometimes to get the tablet out of its hold down spot. It does protect it well though.
Ps. I mainly work on GM vehicles. Since its a preference and this model scanner should do all I need.

Best tool for the money!
This scan tool does everything my much more expensive tools do, plus more! What a great tool and great price. Great interface and fast. Updates are reasonable too!

Very satisfied with the functionality of the TOPDON One Lite
I am a very stubborn DIY'er and would rather learn something than pay someone else to do it for me. I bought the ONE-Lite since I ran into many of the limitations of having just a code reader and a few data steams. I have used this on several cars and am very satisfied with the easy to navigate and understandable functions. I had a hard time choosing between several manufactures and after a month of intense comparison and a budget I went with the One Lite. It has allowed me to do more than was advertised including re-flashing and programing a used ABS Module which one Dodge Dealer said wasn't possible. I was told I would have to use a laptop and the J2534 Pass-through but was able to do it all through the One-Lite. I love the Topology mapping and the data graphing options that are so easy to use. The bootup is fast and link up with the VCI is also very quick. I can use it half-way down my driveway and still have a decent wifi connection to have full functionality. I would like to see the same repair information link to a diagnosis as Snap On has but for the money the One Lite is deal of tool! It has paid for itself without even breaking a sweat in the Florida heat! Thanks TOP DON!
