Good to very good performance with a little room for improvement!

The scope of supply:
It contains the keyboard itself, the protective sheath, and a charging cable for the keyboard. A power supply but not ligt in, so you either loads the keyboard via a USB port on the PC, or a suitable power supply with USB output connects (such as. The power supplies of most mobile phones), which should be taken to ensure that the output voltage the keyboard corresponds to specifications!

For protection bag:
All seams are neat and in general there are no errors on material. The lock is magnetic, strong enough to hold and easy enough to open it quickly. Interior is lined with black rubber the complete shell. This allows not only the keyboard placing non-slip, special tablet comb easily be placed at any desired angle. The tablet itself is clipped in a light gray, slightly transparent holder. The back remains therefore always spared from scratches. The bracket has cutouts for the camera, and all other ports on the tablet.

The externals of the keyboard:
Compact, lightweight, handy and just 6 mm thick it is. The outer shell of the keyboard is made of matt-black plastic, which makes them slightly less prone to scratching. Visually, a quality image and also at the processing can not be faulted (no dirty edges, etc.). There are four small anti-slip dots at the bottom of the keyboard. Provide on other surfaces than the protective sleeve to prevent them for enough grip to slipping the keyboard. Also to be found also on the top two of these points. These serve as spacers when the keyboard in the envelope "on" the tablet is transported.

The keyboard in the practical test:
The first time, fully charge the battery in my case took nearly 3 hours (via the USB port on my PC). Turning on and connecting the keyboard to the tablet (tested with the Galaxy Tab S 10.5) worked quickly and easily. Also customizing the layout (if desired) is simple and works without complications.
The feeling at the keystrokes is pleasant and slightly springy. By transferring with Bluetooth 3.0 also comes with about 400 characters per minute into existence no noticeable delay. Despite the compactness most keys (exceptions are, for example. # Or Backspace) only minimally smaller than what one (17 inches) to expect from a notebook keyboard. In addition, the keys are not directly against one another, but in all directions have a small distance to neighboring keys. This minimizes typing errors in my experience clearly and makes work much more pleasant.
Something worse than the key cuts off the touchpad. Close to the edge, it reacts only very roughly and partially not at all. You keep your finger halfway in the middle but it does the trick. But even then navigate the pointer designed a little hackelig and cumbersome. If one wishes, for example within a text to a specific location you're better off with the arrow keys. One reason is that the pad in relation to its width is quite low. Although you can easily adjust the sensitivity under Android, but I personally feel navigating through keyboard shortcuts to be more pleasant. With a little familiarization period like one or the other but also consider staying at the touchpad. On the positive side, however, that the width of the touchpad makes it very pleasant to use the multitouch feature for surfing (and scrolling) on ​​the Internet.

Other:
The connection and use with other devices worked without problems. So I have the Tastaur eg. With a smartphone (Sony Xperia Z1) and tested via Bluetooth adapter as an input device for my Raspberry.

Wear:
The keyboard is now for about a week in daily use and works perfectly. Only a few minor, barely visible scratches have been added (for keyboard and envelope). This is normal in my opinion, to perfectly normal signs of use, since the envelope is transported by all kinds of other things in your backpack.
Otherwise, so far showing no signs of wear.

Conclusion:
The keyboard and protective case do exactly what they should and indeed good. To create longer works, articles, etc., a tablet is in any case limited. So this is not a negative point to the keyboard in the proper sense. Anyone wishing to obtain the keyboard to complement the Tablet mainly pleasant to write on the Internet to surf and the odd email, is well advised with this product.
