The yoyo One is a modern yoyo, that makes a lot of fun. Loop tricks are possible, but actually it's done more for string-tricks (greater gap width than a pure loop yoyo). Through the ball bearing is a good freewheeling given (sleeper). Responsepads and ball bearings are mounted It is engaged by the cord and go. The meaning of the second bearing has not yet opened up to me really - for me it had the same diameter as the first, pre-assembled. If it is intended to replace: Thank you. I actually had a wider second bearing expected to allow nichtresponsives yoyo. Then you have but a so-called "bind" command, so that the yoyo back rolls up, and as long as I can not to anyway, I need no other camp. What is possible with the yoyo? Quite a bit - the rookie stuff all (sleeper, walk the dog, rock the baby, split bottom mount, man on a trapeze, and the rest of them on the Internet, there are some movies where really cool advanced stuff presented it. become... If anyone has interest in ersthaft yoyo games or will retest it even more thoroughly, I would definitely recommend it only to order from the outset some spare strings. It makes sense to replace the string in time before it breaks in a strong union and the yoyo then ends up somewhere where you will not have it guaranteed ... Who wants to do with yoyo, hereby can not go far wrong. . For children perhaps until 8 o 9 J. (like all yoyos with ball bearings - are, of course, but different talents with respect to the motor skills). Compared to "Fast201" I have also and that was often advertised as THE Einsteigeryoyo, I can only say: clear recommendation for the One. The Fast201 has a very aggressive, not to say too aggressive response system with small plastic spikes. The sound when turning is naturally spectacular - the consumption of strings as well. And: a rapid wind-up with a single snip motion fails mostly because the teeth take up hakelig. In the long run, the untwisting of the cord by hand but is simply too annoying - for me a KO criterion against the fast. Wind-up trick in One the other hand, without any problems.
