A great blade from Butterfly. I personally love the feel of this maginificent blade.
It's speed is great, nothing crazy but enough to hit killers.
The spin is quite something to talk about too, it has a good balance between being stiff and being flexy, but it has just enough flex to provide great deals of spin (with correct technique of course).
The control is also one of the greatest traits of this blade, being not so quick and responsive, it has a good amount of control.
The feel is the best part, it has little vibration, but just enough to feel it.
Its durability is fine too, have been using it for a few months now and up to this point no signs of being used (even after some small throws
The handle is quite comfortable and big enough. Some people complained being too small, but I think it is okay (for mid-sized hands). Also I like the blue colors it features and the logo is also something really cool.
Only thing I can mention as a drawback is its price, isn't it a bit overpriced? Of course, it shouldn't be a problem, because we usually don't replace blades as often as rubbers, but still its price is a little bit too much, in my honest opinion. On the other hand, if you care about that and look after that properly, it shouldn't be a problem using it for years before having to replace that with a new one.
Essence is, it is a great blade, if you need speed, spin, control and feel, you get this. No regrets. I don't think I will change this one, ever.
