A good gaming mouse Wireless Cheap

I can not say it's the best for the price - but it is certainly very good.
Pros:
- It is great for someone with a big hand and fingers.
- It is ergonomic, to a certain extent
- The buttons work as they should, and you can use the TeckNet driver to change the other two keys
- Works on all surfaces
- Large buttons Right, they are useful!
- It seems to be sustainable - it already felt 3 times and still works like new!

drawbacks:
-not very accurate. even with a high dpi, if the mouse is not completely stable, it will not be accurate.
-It Is much too large for a portable mouse.
-the two additional buttons are hard to reach when playing, so they are mostly useless on action games
- Nothing more to date.
