So why only 3 stars? Unfortunately, the cup is there where the volume buttons and mute switch are already broken in two places, because the material is just not strong enough there. Here the buttons should have been completely left out - mainly because the rest of the shell sits so well that this still holds perfectly! I then slightly filed down the plastic because the cracks were a bit sharp. Now the buttons are also more accessible.
Overall, a good bag for a good price - and if they would Snuggling nachbessert something in the plastic shell also 5 stars!
