I just received my commuter case today. I found the fit to be very good, the rubber flaps that cover the lightning connector and the earphone plug to fit firmly in place. The case over the volume and power button are easy to use with a firm (but not hard) press with a great tactile and audible feedback. I have spine damage with a reduction in hand strength and find it easy to press the buttons.
As in anything, these are my opinions but I am happy with the case. It gives a nice feel, doesn't snag when removed from my pocket, and it does come with a screen protector (which I don't use as I keep my phone away from my keys and i have never found one that I liked).
