For those for whom the proportions are not important, my recommendation is the full-size Logitech K 275, which features two different connection ways (radio and bluetooth). Simply a blessing, whether for the office or the home. Our K380 is a wonderful option because of its compact size. It is possible that there are less from other manufacturers; however, we did not check. Because I'm used to the notion that Logitech is synonymous with excellence, I decided to go with them. Different advantages: Despite its diminutive size, there is no digital block contained within it. In order to achieve minimalism, one must make a sacrifice of some kind. It takes no time at all to switch between different bluetooth devices.) On the other hand, I was under the impression that in addition to the connection established through the bluetooth module, there is also a connection established through the radio module. However, I was wrong; it is not in that location:( I skimmed it on the website without paying any attention to it.
