Unfortunately, poor contact of the keys after 6 months since. Many keystrokes are not arrived at the PC. I have permanent repositioning missing letters.
You see it, the key is almost never Großbuchstaen. And I write not so much.
Another keyboard was newly broken. 8 keys down does not go. Sent. came after 6 weeks with "repaired". what was? exactly the same error is still. what I call quality repair
CONCLUSION: Buy, amazed, tap and then thrown away after 6Moaten.
(Errors from the keyboard and are not nachgeessert)
