he logitech G5 Mouse is really one of the best Gaming mice's out there. This mouse have some really great features. With a simple click on a button on the mouse you can change the DPI in to three different modes. On under side of the mouse there is a little cartridge, wich can be slided out from underside of the mouse, with this you are able to change the wieght of mouse! The mouse have an over all great look, and the cord is made of braid fibre, this gives the mouse an even more quality feeling. This my absolutly favorite mouse, i have only had great experince with this mouse. There is also an updated version of this mouse wich i own ( I own both of them ), The scroll wheel is made of rubber and really feels great in the hand. The mouse is mostly made of some kind of Hard plastic material. I really recommend this to the gamer!
