How to Judge the superthin cutting discs quality by Appearance?

How to Judge the superthin cutting discs quality by Appearance?

* Observe the surface - should be flat and smooth. also checking the backside ( the surface without labels ) to see if all the area with same color, if not means the abrasives density is different.
* Observe the edge - should be little bright.
* Checking the inner surface of the metal ring - if there are abrasives grain ? if so, then will have some problem when fixed to the angle grinder.

* Throw the disc to the ground, if heard crisp " bang", it's OK.

Anyway, this just the general judgement way about the superthin cutting discs performance.
