When searching for a new mouse I came across this one from SteelSeries, what drew me to this mouse other than the fact it had a wide array of buttons to program for Wow is its size. I looked at a multitude of mice from Razer and others but one thing that they all had in common was they were rather small. As an average sized guy I have a pretty large hands and this mouse although it looks pretty large, fits perfectly in your hand.
Almost all of the buttons are placed appropriately meaning they are comfortable to use regardless of your setup. The in game interface is a lot better than the previous Wow gaming mouse from Steelseries. You can bind the buttons to your hotkeys with ease and change them on the fly through the in game options. In my case I play a mage and use the buttons on the mouse for miscellaneous spells such as blink and food summons, as well as a few key abilities like Counterspell. It's entirely up to you though what you use the buttons for but beware not all the buttons work outside of Wow so if you plan on using it for other games not all the buttons are usable.
The customization carries over outside of the game through the specific software you can download for the mouse, it allows you to adjust your dpi, button config and change the colour and glow setting of the mouse. This is another aspect I love about the mouse, it's overall look. Designed to resemble the bringing of the Cataclysm Deathwing it has a burnt armour kinda look to it and you can choose which colour and how bright/fast it glows.
Overall this is a very smooth and customizable mouse for people who love Wow or those who just want a bigger heavier mouse for gaming or just general use should defiantly give this mouse a look.
