If you don't care about how big or little your mouse is, then go for the Logitech K 275, which has both wireless and Bluetooth connectivity options. The perfect solution for the home or workplace. Okay, so our k380 is compact and effective. I'm sure there are less options available from competing manufacturers. Because I know that logitech products are reliable, I opted for them. The lack of a digital block is a trade-off for the compact size. For the sake of minimalism, certain things need to go. Bluetooth allows for quick device switching. Cons: I was under the impression that the radio module could also be used to establish a connection, in addition to the bluetooth one. I was wrong, though; it's not there. I skimmed it quickly on the website.
