Arrived today
Ordered it from Amazon
It's awesome!!
Top load like most cases instead of end load like the Casio 650.
Conventional handles instead of backpack rig
Well padded and very appropriate size. It has velcro straps to secure the board in place. Costs $10.00 more than the 650 and unless you are a fan of the backpack straps, seems like a great product
