Multi-device support for the win!

Everyone and their dog makes a mouse- Logitech, Razor, etc etc. What sets this Lenovo Bluetooth wireless mouse apart is the multi-device support. If you hop between multiple laptops - there are 2 bluetooth profiles built in- so it is super easy to switch devices and keep the same mouse.
Excellent Mouse!

[This review was collected as part of a promotion.] I love this wireless mouse. It has not skipped a beat since I have been using it. Works perfectly and I’d say it’s the best mouse I’ve ever had.

What battery is required for the mouse, AAA or AA?
This Lenovo Multi-Device Wireless Mouse X9 Edition actually doesn't use AA or AAA batteries. There is a rechargeable Lithium-Ion battery built into the mouse, allowing for lighter weight and longer life than AA or AAA can provide.
