This is a powerful auto diagnostic tool. For its price, I can say it is the best on the market. However, it has some weaknesses that I want to point out.

Printing the diagnosis report is a bit challenging with this tool. That is because the print button is designed for the bespoke Launch Printer. You might be forced to install a different PDF viewer that is compatible with your printer.

This product cannot also check battery health and crank voltage, and performance deteriorates if different PIDs are accessed concurrently.
