＊No price negotiations or dedicated listings. VANZY 2.0 Ring Mouse Bluetooth Wireless Black for PC Windows Mac Android iOS [Included Items] Instruction manual / Spare silicone ring / USB cable Purchased new on Amazon in July 2023. Used a few times, but haven't had much opportunity to use it and have been storing it. As of August 2025, I tested it before listing and found that the BLUETOOTH connection is prone to dropping when using the Air Bar mode or Gesture Bar mode, which are used when the mouse is attached to the charging cradle. This may be a defect. When used by taking it off the cradle and wearing it on the finger, it worked normally.
