If it's a premium device and the monthly/yearly is like 5$/60$, so after two years, it makes 120$, after four years 240$.
My mouse is a Logitech wireless. Small, light, good fit for my hand, worked on every surface I ever moused on, one AA-battery lasts for >2 years in my use case (I fed it a rechargeable with 2400mA, will last for centuries).
I payed for it 40$ or so. It came with a keyboard, wireless, one AA-battery. More I don't know, never used it actually.
So, yes! I won't buy.
