Need extra wide window mount

[Cheaptoad]

So, I have the supcase on my phone which makes the total width a hair under 3.5".

So far the widest mount I found was 3.5". Either that or go to a tablet mount.

I currently have an iottie one touch. I really liked that one but it's a little to narrow.

Any suggestions?

Mountek opens to just under 3-3/4" with the pads in place. I know it's not a window mount, but I've been using them in my cars for years and love them. (My phone is just over 3.5" wide and I have no problem.)
