PROS: I like that it is a slim carry-on that holds your tablets and a few accessories. I basically purchased this product because of the design and is something that came closest to what I was looking for in a slim backpack or carry-on. I took a chance on buying this product for my Surface Pro 3, but it just barely fits with the Surface Pro 3 Urban Armour Gear (UAG) on. Without the UAG, it will probably be a better fit. Overall, I'm pretty satisfied with my purchase.
CONS: This was probably designed for iPad Air or similar size tablets. If there is one of this same design for 12 - 13 inch tablets or laptops, I'd probably purchase that instead.
