- ergonomic, clear and controlled pressing, very pleasant plastic material.
- No software for fine-tuning the mouse A very hard wheel, if you use the mouse to actively scroll through the text, then the fingertip starts to hurt. In addition, the scroll wheel is very noisy. I would like an intermediate DPI position (like xtrfy -1200) because it turns out too sharp a transition one position is 800, and the next is 1600
