Topdon AD500 it's awful.
Topdon AD500 it's Not a plug in and play, you have to login through wi-fi or none of the apps work, then there's to many bugs being fixed as it's forever updating, if it's not updating it doesn't recognise your password so you have to try and reset it on the screen keyboard that's tiny for a man's fingers, all this before you connect to the obd. Looks good on the advert but to many bugs and updates, one to avoid.
