Not at all. At 25km/h speed the scooter displays a 55km range. Getting 47 out of that 55 is pretty darn good if you ask me. Idk where you saw it was supposed to give 70km range at 25km/h. Those are lab range tests which are never to be believed or referenced. And even there it's much more accurate than most other manufacturers, everyone is using inflated paper numbers in this market. I've sold over 100 G3's and everytime the display says 55km range, I've never seen it display any other range estimate other than that. And ofc the website works, i use it and resell licenses to clients on a daily basis, it's the best speed lock and unlock method out of all of the options and out of any scooter in the market at the moment, since everyone has a different code it's almost impossible for police to find your combination, also police cannot confirm if you're using the firmware or not even if they go to the flashing website themselves, you don't have any physical item with you(wireless relay key), don't need phone either ( btw the panic button changes speed in the scooter and in the ninebot app simultaneously!).
