I am satisfied with this blade. It fits a developing player because it is very controllable, not too soft or hard and because it encourages a good technique (-> you have to create some speed from your own). I tested this blade with the adidas p7 and that is a very good combo. I'm able to create a lot of spin and have good control. The dwell time is good and I didn't notice a lot of vibration.
The disadvantage is that it is not so fast.
