1) the price is a steal for the quality of the product.
2) the installation was immediately on his PC. Plug and Play, no driver problem but perhaps he already had on his machine ad hoc Driver?
3) the grip is good although for large hands (his case) mouse benefit from being more elongated to better rest the wrist.
4) the ability to adjust the weight of the mouse is even more did our gamer has discovered that in a second time (we had misplaced the manual which means that its use is instinctive!)
5) he has not used profitably compete immediately because he needs to get used to the position of the buttons on the left side to handle with your thumb.
This is an excellent niche product and a good price / quality ratio. Recommended.
