Good keyboard but with problems with SSD disks and USB3.0

After a few days I changed the keyboard from an old computer to a new one. And thus began the problems: The keyboard delayed at irregular intervals typing. After about 20 seconds, you could continue to work. The keyboard would then declined almost to Amazon.

The solution: In the depths of the Logitech Forums can be found then the following instructions:
1) The radio transmission can be disrupted, the 3.0 interface are operated on a USB, the recipient should not 3.0 ports are plugged into the vicinity of a USB device by ...
2) The receiver should not be operated near solid Save as SSD hard drives ....

But my computer happens to have both, I create from neither USB 3.0, yet I'm building a SSD hard drive again just because Logitech's development not under control.

Logitech now offers a little shirt-sleeved solution. You get sent to a registration within 14 days of a USB extension cable. Have this ordered and sat in the meantime another USB extension a. The problem was fixed immediately.

Thus, from a really good wireless keyboard and a limited good and "almost" wireless keyboard with bland aftertaste.
For the keyboard itself, I give 5 stars for the drawbacks, there are 2 star deduction.

Note to Amazon: would be fair to mention the user restrictions in the product description!
