Trying out more reinforced cases (like Spigen, etc.), I ended up again with this one. The reason is that it is very thin, it goes in and out easily, it doesn't have a ring that I didn't like to put it in my pocket, and it doesn't add bulk to the device in case someone wants to have it in their pocket instead of hanging it.
In terms of protection, this specific case mainly provides protection against scratches and not against falls due to its thinness. If you want a case that is more resistant to falls, choose another one.
