One is the black water mud version, which is the high-precision version. This is probably 500 yuan.

One is the Audi version, the low-priced version, and this one is cheaper, 300 yuan.

Although it is the same ball, the performance of the two versions is very different, and it has been worn for a long time. The design and surface treatment of the concave spherical wall are also very good, with a strong sense of idling. However, it is said that the horizontal skill of the ball is not good.

The swordsman can't compare with PS and NS, so it's hard to say. 1 It is completely possible to idle without adjusting the rope. Depending on your skill, you can also do low-level balls such as thousand-machine phantom light waves without any deviation. If you are not skilled, you can't do any ball.

If it is Audi version, Dragon Fire 2007 Taobao shop can do it, 288 yuan. The packaging is original, and there is no Audi logo on the front of the high-precision version. If it is a high-precision version, buy wangyichen 20080818,488 yuan.

Idling or something depends entirely on how you modify it. If the modification is good, it can be done in ten minutes by adjusting the rope.

Also, why does the landlord have to buy this ball? For example, there are many good balls in 500 yuan, especially the IZM of YYJ in the United States and the signature ball of world champion Hiroyuki Suzuki, which is better than Bauhinia and between 450 yuan.

Supplementary answer:

That's because of your technology. Don't always focus on the ball. Most of the problems are your own. IZM doesn't sell 450 yuan at such a high price because of its high quality and good performance. Moreover, the ball was made by Hiroyuki Suzuki, who won the world championship for three years in a row. You are still worried about the ball made by the world champion for three years in a row. Moreover, the production company is YOYOJAM, an American professional brand. The iron ball was developed by this company and patented. Those iron balls of Audi Oda can be said to be pirated iron balls of YOYOJAM, and IZM is a plastic ball, which is not afraid of falling or bumping. If you don't trust YOJMA, then I can't help it.

And the landlord, please see clearly. The one upstairs is copying my answers. This kind of person is like a pirated dog.
