Ergonomic but sorely lacking in precision.

The ergonomics of this mouse is no doubt but its displacement principle greatly reduced accuracy. Indeed, using a traditional mouse the point of rotation / movement of the latter is located at the wrist, the sensor / remote wrist is small. With this type of mice, the presence of the plastic wrist support, the point of rotation / movement moves at your elbow. This means increased strongly positional faults. So you play perpetually with DPI button to refine your movements and you tense up the muscles of the forearm.

Positives:
- Touch, sound and smoothness of roulette;
- The position of the DPI button quite handy
- Ergonomics course

The Bad:
- Precision as needed;
- Adapted the hands size 7-8 (8 for me);
- Back support that gets stuck / hill in the wrists shirts and reduces travel.

Personally, I turn now to an inclined mouse.
