Very good but rigid mouse click

Most:
- Adjustable dpi
- Good ergonomics (quite big mouse that feels good in the hand)
- Goes out alone after 8 minutes of inactivity, and reactive in a click, so economical, no need to bother with an ON / OFF button does not exist elsewhere
- Silent Wheel
- Good value for money

Cons:
- The left click is quite rigid
- The title says "gamer mouse", but for me this is not the case because:
* No more buttons than a regular mouse (right click, left click, scroll wheel, dpi, previous, next)
* Simple optical sensor (like all ordinary mouse, but it is specified in the description)

CONCLUSION:
This is not really a gamer mouse (still note the adjustable DPI up to 2000), but a very good despite regular mouse left click a little stiff.
