First, the plastic is very thin, the hull is badly adjusted on the left side. For, due to the large opening to allow access to the SD card, the hull is limp there. So in case of impact on that side, the hull will be ineffective without fail.
Second, there is access to the SD card, very well (personally, once in place I did not hit often), but not magnetic charging port. Or, next to the SD port, there is the USB port, but the one I use most often it is the magnetic port.
Third, the finish is very bad too. There burrs in many places. I even have a sensor (microphone) which is blocked half.
I had to go with a cutter to correct this and return to normal opening there.
The only positive point is really transparent unlike some shells that advertise this and finally a little white.
In short, this case may be very well for other models, but certainly not for Xperia Z3 Compact, even at low prices.
Personally, I prefer to put a little more expensive and whether to have a good protection of my device. But above all, have access to all features without removing the shell.
