Useless without the Nano USB receiver
The keyboard is beautiful and exactly what I thought I was looking for. Unfortunately Logitech makes two versions of this keyboard and both have the same exact model number. The Logitech website is useless in helping to identify the differences even though the keyboard a model number, part number and part id number that are all different. One version of the keyboard that uses the "Unifying" USB receiver and the other uses the "Nano" receiver. Logitech's website lists the "Unifying" software first with a note that if that doesn't work then use the "Connect" software.
Why does this matter? Simple. Logitech no longer sells the "Nano" receivers for the keyboard and worse, not all "Nano" receivers are compatible with the keyboard. Again. Logitech does not differentiate which "Nano" receivers are for mice only, or compatible with this keyboard.
Do not buy this keyboard unless it comes with it's own "Nano" receiver or specifically states that it uses the "Unifying" receiver otherwise you will just have a piece of good looking quality trash.Read full review
