I like all the buttons and amount of options it gives you. I can remap every button, customize the lighting, save multiple profiles with different buttons, DPI settings, and lighting, and even set it to automatically switch profiles when you launch a program or game. It's pretty awesome. The ergonomic design made use and operation very smooth. The extra weight pieces offer great flexibility for different hand and setup situation, like sometimes I want it to be more sensitive and easy to move, while in other games I prefer more stable operation such as in flight simulator. The auto-click button is super helpful I tried it a couple of time but haven't seriously used it in formal games.
