Got the bag ordered because I usually carry my smartphone on a belt. The bag is very well made and looks really good with the blue / black denim. Front pocket a Velcro closure and a second compartment has where you can accommodate from smartphones such as accessories or just can use for other things. The Optimus 4X fits perfectly in the pocket even with the attached silicone shell that is around to my Optimus.
Mir is made slightly too large personally only the belt loop. This could be narrowed, particularly for smaller belt. But is not an obstacle for me.
All in all, a good bag that I would recommend them.
