i got my Frag pro from Nelson yesterday. Took it from a test drive on MW2... feels really solid compared to Fragfx v2. I have both and to be honest the V2 is amateurish at best.. The sensitivity for the pro is a lot better. The plastic they use are no longer the cheap pasar malam plastic like in the V1 and V2. The only down fall is the battery run out of juice pretty fast. So you have to buy a rechargeable battery. Overall i would say this is the closest thing you will get to Keyboard and mouse gaming. I would give it a 9/10.

here's my view on the new FragFX pro
BUILT
The built for this new toy is the best out of the 3 version of fragFX
the mouse built is big and quite comfortable on average adult hand
and the 3 AAA batteries do help the weight of the mouse (fell like razer mouse  )
but the Fragchuck (the one with analog stick) is too big for my liking
when i need to zoom I sometimes wrongly press the "F" button (this is for slowing the movement of ur target cursor,so call works for kaki snipping)

PERFOMANCE
FragChuck
As i was saying earlier the fragchuck is big and this baby suck up battery very fast ( i mean fast like u left it in two days then the battery out of charge  )
Mouse
Ahhh here's a good new bout this mouse,the new feature bout this mouse is u can move ur view  without moving ur mouse.
this function is done by moving ur mouse wheels to the left or to the right.very useful when there are someone sneaking behind u  .
For the bad part is,the movement for the mouse is very sluggish compare to FragFX v2,even after new firmware update this baby still feel very laggy

VERDICT
If you're planning to buy FragFX ,I personally recommend FragFXv2 due to it's respond and function.
FragFX pro is still in testing phase for me..a new firmware might fix it but the future of it is still unknown

Do post here for any question regarding FragFX,FragFX v2 and FragFX pro
I'll try to help up if you having any trouble with it..

I'm using Fragnstein. More superior    but hard to get
