Some pros: Mac OS X is intuitive and easy to use (gestures); Maintains a charge over a very extended period of time; Cons include the following: the coating on the legs is not very durable, thus you will need a mouse pad; Because it is feasible to implement a cell in the mouse in which to store the bluetooth adapter, there is a possibility that this will occur. I establish a connection to macOS without it (this may cause data loss).
