The requirement to be able to operate with an external display that is attached to the MacBook led to the acquisition of the monitor. This keyboard was the best option for me when considering all aspects, including cost, aesthetics, and additional functions. The "full production capacity" of the touch printing was reached after only a few days of operation. Someone might get lost because the keys are circular. This is an elaborate hoax. There is not the slightest bit of a problem with this at all.
