I purchased this bag for my big tablet. They can look very sophisticated and robust, yet is very easy. The outer material is made of a plastic fabric which is very resistant. Inside is a foam lining with studs that protect the device well. The zipper is smooth and makes a durable impression. In the small outside pocket accessory fits into it. It has directly under the impression that this bag protects the inserted device perfectly. I got to the already test out, as the tablet in his pocket from the table crashed to the stone floor. There was no damage.
I did it with a Nexus 7 (that's significantly smaller) tried and found that the bag also protects here perfectly, as if it were made for it. By the knobs and the relatively tight fit slips nothing back and forth.
