Ordered these from gohastings earlier this week.
Best part about them is that you can access the Vita's charge port without having to remove the grip. For those of you with a Vita, you understand how fast that battery can run down and how much of a pain in the ass it is to have to put on and off a case just to charge the thing.
The triggers are also really nice after a littlle modification. Glued some felt padding on the inside of the trigger compartments to protect the Vita triggers when the grip trigger plastic makes contact with them. Fits like a glove now.
Another awesome thing about this grip is that the back triggers allow the Vita to rest nicely on a table. Also for those with a Wii U, this grip works pretty well placed on top of the gamepad stand.
Overall this grip is much better than the Batman style grip I also have (unable to access the charge port, doesn't rest nicely on a table or stand).
That's a great tip about using the felt around the PDP grip triggers (inside the frame), I'll have to try that out. I have one set of these grips for one of my two Vitas, and I like the way it changes the feel of the system to be more comfortable. Before I had it, my hands would cramp up (especially on games like Terraria, which has lots of button/joystick activity).
I did have a slight issue with my grip, the Vita tended to try to "pop out" from the grip around the bottom right area, because apparently the grip just didn't quite fit tight enough. I wedged a small sliver of wood (from a toothpick) between the top right area, between the grip frame and the Vita, and it made the bottom right area fit snugly.
The Best Buy tag in the store (and online) said "Clearance" for this, so most likely they are getting rid of these in anticipation of the Slim Vita (which these don't fit).
