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!

Very capable
For the cost compared to other scan tools it is a great value, you can add certain pids to active tests which something my snap on one can’t even do!
