What brand of balance car is more reliable?

I only recommend two models to you.

Millet 9 short-distance walking (9) children's toys (5) auxiliary work (7)

Litbot short-distance walking (6) children's toys (9) auxiliary work (9)

I got 10 in it, with full marks. Why do these two companies own the invention patent of China balance car? There are four in the world, the lower one is more flexible, and the upper one has more functions, but it is not suitable for children's toys.

The upper part is an integrated car with poles, and the lower part is an integrated car without poles, which can also be used as a twisting car.

What about other brands? It is either authorization or the purpose of shanzhai authorization, and it is not to make a brand, but to sell that product and cheat consumers by hook or by crook. I subconsciously regarded it as a shanzhai, and to some extent, it was a shanzhai.
