Surface casing pressed!

Hello There,
I have the "Smart Shell Case" brought me my sleeve for Surface. Today I realized that at the upper right corner is clearly pressed the metal casing (the speaker) and precisely at the height of the hold-down strap of the case. The tablet is never fell off me so far and was always carried in a separate, additional padded compartment in the backpack.
Amazon has the article, although withdrawn immediately, my Sruface However, this does not back safe.
I get back to a simple protective case, even if it was very comfortable with the Case.
In effect, the shell has brought me exactly what should prevent them.
