Another positive aspect is the possibility to load the keyboard in use. Where even during 8-10 hours daily continuous operation even after a year of battery 2-3-weeks holding despite the integrated keyboard lighting, which I do not want to miss (I just do not like lamps at the workstation).
Not well done, the residual capacity display is in the driver software. No percentages, but a three-stage bar from which one can not infer whether the button or by holding a day.
Very handy in turn, the ability to switch between 3 devices. Since I own a Mac Book Pro, a Mac Book Air and Mac Mini, I can use the keyboard quickly with all three devices without having to re-pairing. So I need only a keyboard at work.
I've also added fresh the Logitech T651 touchpad. Even though it was nowhere described, I had little hope that Logitech has integrated the feature in common driver switch also with the trackpad. Unfortunately this is not the case, which is not apt, at least on operation of multiple Macs. I have the function to be asked as a feature request at Logitech - but so far without success. Since the feature is not advertised, the shortage does not lead naturally to a devaluation, the otherwise very good keyboard.
