Ninebot One S2

Advantages: price / quality ratio, very good workmanship

Disadvantages: Very poor standard equipment. Only the wheel itself and charging.
There is no training belt, no stand, no pens, no protection. All this has to be bought separately for big money. I ordered from China, it turned out totally for $ 150, to buy here is 1.5-2 times more expensive.
Beginners on this wheel is difficult, because the handle is very low and if you tie a safety belt to the handle, the wheel will be periodically switched off (when you lift the handle, the gyroscope is automatically cut down)
Big problems with the production of legs. The wheel is very small and has a rounded shape. For shinners, newbies are just death. Protection saves, but it must have time to buy. :)
No speakers and flashlights.

Comment: Experience is still very small, because newbie So far, only managed to kill the legs in the trash and figure out how to ride it. There is nothing to compare. There were more minuses than pluses, but in reality the wheel is great. Just get used to it. Understand how to bend the legs so as not to crush the knuckle and not kill the lower leg. It is also worth buying a stand and a pen to carry. The wheel is 100% met my expectations.
