Good product with secure attachment

I have a HTC One M7 and the device fits perfectly in the pocket.
I especially liked the fact that:
The bag can be very good and reliably secured
In the lower compartment, an additional Powerpack can be accommodated
The universal mounting is done without tools through velcro
Other utensils can be accommodated in the pocket
The device is at least splash-proof.
The bag stays securely in place.

Not quite as nice, I find that
The mobile phone because of the closed bag is naturally hot
The window reflects the announcements and are virtually inaudible.
Both are of course due to the fact that the case is a "closed" and protecting and construct a death you must die precisely.
I find the design due to the associated equipment protection and Secure universal mounting but better than an open bracket definitely.
I would buy the bag at any time
