Honestly, this thing looks like the ultimate vita grip.
THIS REVIEW is fairly brutal, but the device looks great.
The lowest I can find it for is about $50 on Amazon w/prime, or $35 on Rakuten Global (+international shipping).
I might just buy it down the line though since it looks like it would really make remote play and PS1 games so much better.
This seems like it would go great with the custom thumb-sticks made by Markbrochill.
Available in White/Black.
