Some advantages include: easily attaches to a Mac; great sensor; comfortable design; pleasant-to-touch materials; more than a month on a single charge; practical application for configuring a mouse. Cons: You need to turn it off and on multiple times since it occasionally becomes boring (stops connecting to the computer or momentarily stops showing the settings set through the application on the computer). However, it's not really frightful. using a micro-USB to charge. I only have this one remaining item with such a connector; everything else is usb-c. To charge it, you must frequently search for a wire.
