Most:
- Great autonomy: My mouse has held 2 years on a single battery (to lighten the weight), leaving the standby (without putting it to "off").
- Good ergonomics with discrete and well placed buttons
- The décrantage the dial is very convenient to scroll silently or unbelievable speed
- Fast and accurate cursor
The LESS:
- The wheel is sketchy and somewhat capricious
- Click the left and right wheel are risky
- Prohibit Mouse for left-handed
The wheel is undoubtedly the black point of this mouse but its use is still pleasant and comfortable autonomy.
Quality / great price.
