I have not bought a Galaxy Note 2, but I needed a cuff large enough for my Wiko Cink Five.
And its large size allows to slip my wiko with its silicone cover, the phone fits perfectly in place and allows the use of touch as agreed. While the cover is not perfectly molds to your laptop as it is studied for a Galaxy Note 2, but finally allows to have his laptop with you 5 inches during his jogging, and it's not ugly!
I read the comments for size, but as we see in the photo there are two notches to spend the cuff, and the farthest recess leaves a large margin for the "big guys", Arnold Schwarzenegg excluded.
Finally, sealed product, and of good quality. With a prime location for the key.
