I use the Razer Naga Chroma.
It costs a bit more, but has alot of additional keys for shortcuts.
These can be programmed for each programm individually (It switches automatic).
The possibilitys for the keys are nearly endless. Personnaly i manage sound, Shortcuts, Copy/Paste, even whole basic sentences (like E-Mail Ending) all with my mouse.
From the feeling, it weights a bit more. The DPI can be configurated. (1000-16000 16000=Way to fast)
It has a connection cable. There is also a version without, but that one is rly overexpensive.
