That cover is awesome especially for watching movies or videos without having to hold the phone all the time, which can be strenuous.
Following video instructions hands free makes it also a useful tool. And it closes just like a book when done.
The gel cases obviously slip in and out of my pockets much easily. The olixar design allows a subtle edge all around the phone, preventing any contact with another surface.
Depending on how the phone is used, it could be a benefit to prevent the launch of unwanted functions that sit on either side of the phone.
Sony monolithic/omnibalance design language makes the cutouts for the buttons, mics, the main camera and plugs easy to work with, and they respond as expected.
In regard to to the protective glass, the screen responds as if there were none. "installing" it felt like it might be a project, but I only had to make sure there were no debris or particles around while placing it on the phone. Following the instructions helped.
