An indispensable tool for emissions

Received this scanner with little expectation. I've had several small, inexpensive tools like this to check codes and maybe some monitor checks, but this one worked quickly and threw up a few surprises. Even the data you see is too big for such a small tool. The only element that could be improved is the construction = but the amount it is capable of far exceeds the weight of a lighter construction, especially for the price.

Pros
