Negatives:
- Battery does not last very long (compared to the MX Revolution)
- In zoom mode, you have to constantly re-insert the USB receiver, the mouse stops responding correctly
- Left-Right move the mouse wheel is very much getting used to
- The middle mouse button can be pressed hard
- Scrolling with the middle mouse button is annoying. Description: to scroll quickly down the screen jumps
again slightly upwards. ie, you have to scroll down a bit back to the desired position on the screen
come.
Conclusion: The negative points are so severe that I not recommend and advise against the purchase.
