It's highly configureable. The palm rest slides back and forth, the thumb rest moves in and out for wideer/slimmer hands. It has multiple pieces that come off which are replaceable with different shaped pieces so that you can get the absolute best comfort fit. http://store.madcatz.com/categories/Mice-Parts-and-Accessories/
Razer naga 2014. On top of this, I am using the razer goliathus large edition, so it is the length of my razer blackwidow chroma. Serves well as a mousepad On top of having the million buttons on the side, the mouse wheel can be moved right/left, which can be customized. I use it to go back and forth between pages. Along with all this, there is a downside. The 12 buttons on the side do not nave their own dedicated key entirely, so I can't use them in push to talk well. Instead, I have to make the button "1" bound to "\" and then set "\" to my push-to-talk. Other than that, works great. Razer symbol on the front fades in and out, and it's green.
I haven't got a Logitech, Zowie, Razer, or any mouse like that. What I have is the Nemesis Kane Pro, or as most people will probably now know as the "poor man's keyboard & mouse bundle" because all it costs is £20 for both and I got it from a computer fair 7 months ago and still no problems at all except the keyboard drivers being a bit odd at times but that's only if you put in a new mobo (as I upgraded from an M5A78L-M LX V2 to an M5A99X EVO R2.0 along with a CPU upgrade from the 6300 to the 8350) xD http://www.amazon.co.uk/Sumvision-Gaming-Keyboard-Mouse-Adjustable/dp/B00J2U3D7G
At the moment i have a razer abyssus 1800 , it does the job , lasting well , i needed a cheap mouse to use , got it from pc world , im not into expensive pc peripherals since i know i will end up ruining them , i have a $3 headset shipped from china , and its lasted me as well as when i had a $40 headset , so i mean i guess its just whether you prefer design to pay for
