It works as advertised user-friendly. The battery held charge for a long time. I mean, this is a great tool, especially for the price.

Life-Saver for Semi Truck Diagnostics! I bought this scanner after persistent EGR/DPF issues with my semi post-repairs. It's been a game changer. The compact design with its secure-hold case makes it perfect for roadside use,though I wish the screen were slightly bigger (still perfectly readable). It auto-detect my truck initially and it delivers pro-level results. Reading stored codes and live data helped pinpoint why my rig felt sluggish.Super user-friendly and pays for itself instantly. For any truck owner dealing with emissions systems, this is an absolute must-have. I would highly recommend to fellow drivers!

The media could not be loaded. This Launch heavy-duty scanner is a game-changer for anyone working with larger trucks. The touchscreen is incredibly user-friendly and intuitive, making diagnostics fast and hassle-free. It supports bi-directional controls and handles DPF regeneration with ease—no more trips to the dealer just for a reset! It’s rugged, reliable, and worth every penny. Highly recommended for any fleet or diesel tech looking for a solid diagnostic tool.
