There was a problem with the previous autoscanner, it did not want to connect to my android phone, I had to hand it over. There were no such problems with this scanner, it connected quickly, without lags. There was also an instruction manual in the kit, everything is written in detail what and how to use it. It helps to save on diagnostics in a car service, 2-3 times and the autoscanner has already paid for itself. Helped reset the error with a burning check engine, identified it as P0042.
