You can weight the mouse supplied with the weight and offer a wide range of possibilities. A gadget that proves handy. To convince you, try without ballasted max and after you really want to test combinations of weight in order to have the perfect feel.
The slide is quality even on a crappy carpet.
The sensitivity has 3 basic options 400, 800 and 2000 dpi. But the ability to change them or add additional 2 once installed software allows the setpoint after a period of adaptation and several trials have the best possible performance.
Two buttons on the left of the knob can switch from one resolution to another at any time.
A button below the dial to the décranter and vice versa. Friendly but unlike the usual opinion, I do not find ca essential (if not silence it brings).
The dial is used well on top but also scroll down left right (the default). The right left movement also provides a click on each side and promises a real advantage because the movement is natural, giving 2 generic buttons (Redefinable and macro) used on reflex movements especially gaming.
Setpoint The software is simple to install and use.
Very bad point:
The 3 buttons above thumb requires some natural movement. I'm having trouble explaining the inconvenience but it requires a more a reflex reflection. In a situation of tight stake are the reflexes take precedence, not the time to say "to save me I have to click on a particular button being careful not click others." The three forts are close to forcing up the palm and thumb to move the farthest, and curl your thumb to the max for the nearest button. Big hand refrain.
A generic button with an identical system over the mouse, ie a clickable plastic single piece on which the thumb rests, and another 3 here instead of presents were preferable.
Better two good three buttons that bad. Without that this mouse would have been perfect.
Finally you can buy this mouse EYES CLOSED.
