Logitech Trackball MX ERGO

Several shapes of mice are used to reduce wrist pain, and trackball is one of them.
The previous trackball had only a simple function, but the product introduced here has added many features.

• 8 customizable Buttons,
• Connect on two devices at the same time and easily switch between them.
• Dual connectivity via Logitech Unifying receiver or Bluetooth connection.
• Rechargeable battery up to 4 months.
• Adjustable angle ( 0 & 20 degree).

I recommend this product if you work in the office for a long time.
