Here are the results for all Samsung Smart TV users E Series:
Conclusion: Hooray, it worked right away.
Here the experience:
+ The keyboard is recognized in seconds from the TV and the Setup menu opened automatically.
+ After selecting the German character set, the keyboard was ready.
+ Move the cursor on the screen, I could immediately use the touchpad and let flit across the screen.
+ The Left / Right mouse button function is working properly.
+ All text entries in the Web browser, etc. work great.
+ The coverage of the sitting room opening to farthest seat from 8m properly.
- The volume control does not work, but I can live with.
The many other features I have not tested, but I do not need for the smart TV also.
I can not say anything, but in the E series a direct hit on the function at the D and C series. I'm very happy and hope other Smart TV users to have helped it.
Addendum on 12:08:12
On a request in the comments I've tested the function of the keyboard also on my Samsung HT-E5500 system. All the functions described for the Samsung Smart TV also go on HT-E5500.
My additional Conclusion: +++ super keyboard
