The bag for the Surface Pro is really succeeded. It offers sowol for storage with or without pin enough space where it does not wobble without pen and not to go with tight pin. The Velcro is completely consistent. The material makes a very robust and is really well padded. All in all, a successful product. The only that it would improve when the bag is closed, is the right and left on "cover" a small gap but this in no way affect the function. It would just look a bit nicer.
