Very good 15 mice

Very good mouse, allowing you to play games or others, without any worries
You can also set the weight of the mouse via "volumes" included in (6poids from 1.7g to 4.5g + 6poids to insert in a box of 6 pitches, personally I chose the 4 + 2 weight 4.5g weight 1.7g because I do not like having a small mouse, but it's a habit)
Otherwise you can program each button to a program, such as "Increase the sound" "Set pause" or "Back Office" long but rather simple to program, you can also choose the frequency of your mouse, handy for video games
The wheel can also become "free", ie by pressing the button you can see just below it, it down with one simple movement, enough to avoid "Tac-Tac" or damaging

I rather large enough hand and mouse for me amply, if not comfort level is rather well
