Xtool D7 scan tool causes no start

The Xtool appears to not work well at all and actively causes issues on cars, or at least my car as shown in the video. I can’t make sense of it. Seems there are lots of people who like this tool. Idk if these reviews are fake and everyone is shilling, or maybe I just picked 3 cars that the tool doesn’t work with. Either way I’m returning it.
