Hey I’m doing a review of my 2011 version YYF ONE. OK first off I’m am going to tell you that even with the caps out it still doesn’t grind very good. I got the red and it is really light red. I like how you can make custom caps but after you take them out and put them back in enough times they will get loose and sometimes makes a noise. And sometimes it gets hard to get the caps out.
You can upgrade it very easily to a center trac and make it a descent yoyo
The caps get loose after a while
The spin time isn’t that good
Very small gap width
I give it a 6/10
