It fits my Xperia Z snagly, allowing acess to the USB port, the Power button, and the 3.5 mm jack and does not obstruct the speaker. It looks nice and protects the phone. It also looks durable, as I have been removing it from the base to insert or remove the SD card. The case closes nicely with the aid of the magnet.
This is the best case for the Xperia Z at less than £10, highly recommended.
