I use the keyboard with my Logitech M325 mouse. Advantage: I just need a Unifying receiver. The connection was very easy. Simply the Unifying software install and run, turn both devices one - that's it. The software can then be deleted.
The range is with me loose 5-6 meters. Especially handy I find the function keys such as Play, forward Track and back and volume loud and quiet. Of course you need to install any additional software!
For writing behavior. Contrary to other opinions I find the keyboard while writing not too loud, so no loud chattering like old Cherry keyboards. All depends on how to write. The spacing between the keys are super and prevent you type next. 10 Finger writer should therefore cope well with it.
And one more thing: in the keyboard are 2 beautiful Duracell batteries, which are known to be particularly powerful.
Let's see, how long will the batteries
Conclusion: A chic keyboard that has everything you need. Solely a wrist rest and a status light for Num Lock would have been nice. Nevertheless 5 stars!
