Feel the Material
The laser tracks well on the new pad with no jitters or spurious movements when moving the mouse in a straight line, meaning you don't have to constantly compensate for any drift the mouse might experience on poorer gaming surfaces.
Putting in a longer session in World of Warcraft; the mouse doesn't cause any hand cramping or stiffness when you're on an all night raid. I've had trouble with mice in the past where I've had to pinch my hand in further than normal to grip the mouse adequately and this resulted in some serious hand cramping after only a few hours. I call it laptop mouse syndrome.
Overall, I'd say that this rodent belongs among the ranks of top end gaming mice. With its customisability and solid performance, it's become a quick favourite of mine because of the balance between ergonomics and features.
One slight issue I had trouble with, however, is the software scroll speeds seem far too high if you have them anywhere past the second notch. I'd often go flying past parts of web pages I'd wanted to see. Trying to compensate for this under the Windows scroll speed defaults it to the M8000 software setting.
This mouse should definitely be considered if you are looking for a top quality gaming mouse from a top quality name like GIGABYTE, because you are not going to be disappointed.
