Excerpt: The best mouse I have ever used. The shape fits perfectly on my hands (I have fit medium size gloves). I have used many laser/gaming mouse in the past and nothing beats this. There is a huge improvment from the g5 v1 to the v2. The material of the mouse is very different. The g5 v2 has a nice feel to it because it hand will never get sticky or sweaty. The cord is very long.
