Beautiful and very fitting case with a big "but" ...

+ Processing (high-quality feel, supplies, sutures etc.)
+ Fit
+ Cleaning Cloth
+ Price (20)
+ Also Goes well with the device

This is offset by a large negative point which could represent an exclusion criterion for many potential buyers:

- USB port of the device only of limited use

Herein, a holder is an obstacle, you should plug in a USB or devices that go with its dimensions through the terminal itself out.
The bracket includes exactly from the USB slot. This can be guessed using the product photos on the manufacturing side.
With micro USB Sticks probably not a problem, but in all that goes beyond this, the USB port is exposed to unnecessary mechanical stress.
Possibly can remedy with a slim USB extension, almost one would like to take the manufacturer in the obligation to settle such a cable.

But here everyone has to weigh for themselves whether this awkward arrangement could prove disruptive. With Bluetooth and Wi-Fi has plenty of alternatives in terms of the connectivity of the Surface RT, when it comes to data transfer or the connection of external input devices.

++++ UPDATE: ++++

The case fits 1: 1 for Surface RT, reviews which complain that something jumps out, or does not fit, show only that you should bring some peace and fine motor skills, and possibly in trouble in the enclosed - fairness illustrated - guide should look. Nothing is crammed (!), But the casing is only placed on the presentation mode, reingeschoben the tablet, and then closed with the lower bracket for this extra-have some play without losing the necessary support. The tablet is held precisely when designed properly and optimally protected, without any wear on the product. :)
