This Logitech mouse is magnificent. It perfectly fit your hand and buttons are in right positions, so your fingers can easily press it. Battery of this beast lasts for few months and it is charged by usb cable. Scrooll wheel has many options and sometimes I feel that it adapts to application which I use at the moment. Also there si horizontal scrooll wheel, you can configure it for lots of purpose other then horizontal scrool option. Literally every button you can configure for doing lots of things. You can done that with official Logitech software for remote devices.
