I got the PDP Pad today, played with it for GG Xrd and MK9 for 2 hours.
Here are my early impressions:
Most of you have probably heard by now, the pad is very light, I don't have problem with that though, cause it fits well enough in my hands.
D-Pad is great, it's not too loose, you can move it around pretty easily and it's not made of material that will give you blisters.
It seems like you really have to press those micro-switch buttons all the way down for the inputs to register, it will take some adjusting.
I wasn't used to the empty space underneath the shoulder buttons at first, I'd press that instead of the actual buttons, the problem started going away after more practice, there's a pro to this, you can rest your index fingers on the empty space instead of having them in the air all the time, because you don't want to press the buttons accidentally.
You pretty much have to use your nail to press the Share and Option buttons, they're very small and have little space between them.
So far, I'm satisfied with the Pad. In fact, I just unplugged my PS2 to PS4 adapter and Sega Playstation Pad to give this thing more uses.
