Best code reader we've ever had.
Con: There is no explanation of what the "cloud print" feature does and the instructions are very poorly translated.
Pro: It's pretty intuitive and you can figure out how to use it without the instructions. It does live readings of a variety on different measurements. The video I put on here scrolls through a lot of the options that it shows data for. It does live graphs. It really comes in handy when you don't trust your speedometer too. Good for checking your starter, your battery health, all sorts of regular error code checks, but it does more than most code readers.
