Following all the hype, I was interested to try one out and did not do my research before buying - a bad mistake. From initial plug in, it turned out to be unbelievably slow. It needed to update itself and do other admin trivia before it was ready to start, but then it took over 5 min with no indications of anything happening. After a total of 10 min, it showed signs of life and had detected the car and scanned the systems. But the App and device provide only very basic information. Free OBD apps that connect to cheap OBD plugins from China (TEMU for less than 5 Euro) are so much better. No, do not waste money on one of these - I have no idea why YouTubers continue to promote this. Additionally, Carly only sells a subscription, and that is really difficult to cancel so beware.
