The title needs a bit of explanation. I do not mean that all parts of a review are going to be useless. I do mean that some of the terms used in many reviews do not tell anything about the yoyo. Let me give you an example: the term ‘Floaty’. I myself am not sure of the meaning of this word, but I think (correct me if I am wrong) it means that the yoyo is fast and light. I am taking physics, so I have some issues with this definition. According to physics, when a rigid body moves (forgetting about collisions for a moment), it moves as if all its mass were at its center of mass, regardless of how its weight is distributed. Thus, when a yoyo is said to be fast, all that says is that it is light. Thus, ‘Floaty’ is redundant.
Let us look at the big yo. It seems really light, but if you look at the weight of 75 grams, you might be surprised. The reason for this is that the big yo is so large. Perhaps ‘floaty’ means light compared to its size.
Revised Definition of how ‘Floaty’ a yoyo is: How light a yoyo is compared to how large it is.
So floaty depends on the size and weight of a yoyo, both of which can be found in the specs of a yoyo.
Thus, the term floaty is useless. The same goes for the term ‘Solid’.
If you have any problems with this, don’t hesitate to tell me.
