Does anyone here have any experience with the Mystery River Sphinx pack?

I've been searching for a while now as I work my way through different brands, and came across this model today.

I love the pouches on the hip belt (actually big enough to pop a smart phone w/otter box case, in and out, easily). And the water bottle pouch can actually be accessed without taking the pack off or using the busy system. (Looking at hit osprey!).

The pack seems to ride well on my hips. The shoulder straps seemed a bit narrow though. It wasn't a problem at the store, but I wonder if it will cause issues down the trail.

Also, I wasn't sure about the vertical zipper down the front of the pack.

Any input/experience on this pack would be greatly appreciated!

Thanks
