My criticism is directed at the overall perceived quality of the keyboard. For 100 euros I could have stayed more noble materials, such as aluminum expected. Unfortunately, there is everywhere only plastic front and also on the on / off switch at the top. On my old TK820 that was a solid metal switch. Here I have some fear that at some point give up the ghost at all too hard to use. Subjectively, but a good feeling really leaves not this Schalterchen. It is light and compact and the delivery (USB receiver plus extension cable, USB cable for charging the keyboard on PC, manual) is complete. It comes in a stylish package, therefore, and the keyboard is again wrapped in fine paper.
Otherwise, the part is doing what it should, but even here a criticism. All my other Logitech peripherals such as the mouse and the Tatstatur directly to my PC (which I use T830 yes the coffee table for the remote control of my PC as a media PC) are centrally managed through the "SetPoint" software from Logitech. Here you can configure the device for his personal use. Very handy, because even all goes through a USB Unifying receiver. The T830 is even more than the recognized and controlled a Unifying receiver, but a new software "Logitech Options" software must be installed for this new keyboard. Why you can not even manage uniformly under the umbrella of proven SetPoint software does not open up to me. Sure, everything works fine, but I'm a little confused why new software is specially necessary here?
Clear I'll keep this keyboard (they've also directly in the online shop of Logitech for 99 euro bought) remains, but a little pale aftertaste. I mean, it would be appropriate a maximum of 70 euros for this keyboard, but 100 Euro are definitely too expensive.
