Great mouse. I am annoyed with the change in the button placement for mac gestures given my muscle memory from the Master 3, but it's not bad after getting used to it. I do find myself accidentally pushing the button my thumb rests on a lot. If you're used to the older variants, it will take some learning to change the muscle memory.
I bought this to replace one like it that was no longer holding a charge. Of course I have have knock this on the floor over the years. Knowing how durable this was got a ew one. It works just like old only holds charge.
