There is a few keys for shortcuts

 

 

Wireless Mouse

  • Scanning: Infrared
  • Resolution: 1000 / 2000 dpi (adjustable)
  • Number of Keys: 3
  • Mouse wheel design: Scroll wheel with key function
  • Design: Symmetrical
  • Connection: wireless

The mouse has unfortunally no thumb buttons which are very handy to go forward or backward in webpages. If you dont use thumb buttons then this mouse is all you need. To switch DPI you hold left and right mouse button and then turn the mouse wheel. The mouse feels nice and accurate.

 

Charging

On both the keyboard and the mouse, there is LED indicators. When they flash red, you need to charge the battery.

To charge the keyboard or the mouse you need to use the chargin cable into a free USB port and turn the switch to ON. You can still use the device while it is charges, to avoid productivity loss. You cannot charge both mouse and keyboard at the same time, since only one chargin cable is included.

 

 

Installation

Its very easy to get started. Just insert the USB signal receiver into your computer. Drivers are not needed.

 

Conclusion

Cherry B.Unlimited 3.0 seems to be a set of keyboard and mouse where wireless secuity and build quality is in focus. It could possibly be more suited for an accountant than a regular user, which is slimming down the potential user base. It is not designed for gaming or intense web use since thumb buttons are missing.
