Wanted to add that I received my dualshock4 controller mount from amazon this morning. It works rather well I was afraid the nexus 6 would be too big, it looked like it was a solid piece of plastic that hrldbthe phone and the posts on the site seemed to suggest biggest it would hold was a note 2 or 3, which is close to nexus 6 but both are still smaller....but after getting it out I see thstbits actually a sliding mechinism that from what I can see could handle most smaller tablets as it slides out a good 4 inches. Its got spring resistance to pull itbbavk down and hold the phone in between too rubber textured grips that have a small plastic lip that aid's in securing phone to mount. I put it in with a spigen clear case and it held well even shook it about upside down and phone never moved. Seems to do its job pretty well SBD for less than 10 dollars I'm happy with it.
The only problem I found is volume control on the side can get pressed by the mount but I find its only when I'm mounting and unmounting the phone, though using them while mounted is rather difficult as well though not impossible just have to press the very edge if them and again some times this causes the button tobgrt held down by the mount. Not a big deal but thought I should mention it.
The viewing angle is adjustable and comes with a screwing mechanism that locks it in place. Controls of dualshock4 remmain functional but buttons around touchpad and touchoar itself are obviously obscured slightly by the added plastic surrounding them. Not a bad way to spend 8 buck's for what essentially gives you shield style portable PC gaming.
Here's a link once again to what I purchased
thanks this one looks good except it doesnt seem to offer a flexible display postioning system. I might check it out if the one I did order doesn't work out though
BTW this is what I got will be here tomorrow will update once I've tested it.
