The Pixel fits in very snug without being too tight, even with my usb dongle in the side, although it is a small Logitech one – larger ones would be an issue. The outer casing is nice and rigid and is water-resistant so I feel comfortable knowing my Pixel is protected. There is no contact between the zips and the Pixel plus there are pockets to hold extra devices or notepads or whatever you like. I have my Nvidia Shield tablet in 1 and it fits great.
Anyhow, just wanted to share in case anyone is still looking for a case for their Pixel. This is certainly not the cheapest case (especially with the weak Australian dollar) but it was the best I could find and I'm loving it so far!
