Very good quiet wireless keyboard with a very long battery life.

Here everything is actually already been described, however, I would like to address the subject battery charge.
I bought the set on 10.08.2014 and this since about 3 days per week in operation. I had been reloading neither the keyboard nor the mouse. With the keyboard you can see the red flashing LED immediately after the activation of the Einschaltknopfes. This is supposed to light up continuously when the battery needs to be recharged. In the mouse, I had this red LED but so far searched in vain. Now I have you swam and found that it unfortunately can only see under a certain angle from the front next to the scroll wheel, the red LED the charging cable into the mouse. I have contacted in this regard even Cherry. There was thought, however, that this is intentionally so. I find, however, that the LED is attached rather clumsy in mice that get other vendors (Logitech etc.) any better way.
Enclosed is a photo with two red arrows, so that people know how to find the red LED in the mouse.
