Question about Xiaomi Pro 2

I am happy with my Xiaomi Pro 2, with which I have driven about 150 km so far.
I can't say how much autonomy it has because I recharge the battery for my convenience every 20-25 km, when there are only one or two spots left on the consumption indicator. I must also say that I always ride in S mode (the one that reaches the maximum speed of 20 km/h and consumes the most battery).
I don't know the Segway but if I look at the technical data sheet I immediately noticed the difference in weight. The 14 kg of the Xiaomi sometimes are quite heavy during the transport by hand, the 5 kg more of the Segway.......
I also like the double brake lever of the Xiaomi (one electric and one mechanical) on the handlebars.

if you want to do long distances 20 km go back to the pro 2 and what it takes and for what is the ninebot I do not know what it is worth
