Shame (!!!) is the app on Android that is needed to set up, but if you once fought (lasts one day at most - eight to twelve hours), you no longer need this, yes. A configuration on the PC is actually not possible - only Android and iOS with Bluetooth 4.0. This limits the circle of users but a little.
In general I could spend hours still leave here as there Logitech has completely failed in developing an in itself perfect and perfectly usable product ... in order to understand this apparent contradiction, but one has to buy the product well ;-)
Quality and feel are very good, size and handling pleasant. A few more user-definable function keys would have been nice.
I control an audio receiver with tuner, an LG Smart TV and a (Windows) multimedia PC with the keyboard. For the PC I had to ultimately buy an infrared receiver, although the operation could work via the included USB wireless adapter also in principle. Here there is a lack of development division of Logitech a little good will, which eventually does not work, turn off (!!!) was only the PC's. The infrared receiver but I have then used by 5 purchased. So what the heck.
The LG Smart TV, however, could be without difficulty - out of the box - via the USB wireless adapter use (including mouse function), which made me very happy.
Thanks for reading this brief and confused Review! But this technique Adventure Logitech is so complex that you have to experience yourself ;-)
