I used this mouse for about 3 years. It felt very nice in the hand, and I appreciated its good Bluetooth connectivity (used with a Surface Laptop Studio, and connection to a Macbook Pro was also confirmed). The left-click function was a bit unreliable (sometimes a single click would be registered as a double-click), so I am selling this mouse to replace it with the exact same product. Please understand that this is a used item. Communication: Bluetooth Charging: USB-C rechargeable (no batteries) Devices: Win/Mac
