for its price (bought for about 430) fire goods Different pros: 1. Spectacular appearance 2. Additional forward / backward keys 3. The presence of a proprietary application for setting backlight, controlling dpi, creating macros (I hardly use the application, but this is a clear plus) 4. Feels good in the hand nice smooth top surface (what with the runes) and nice rough side surfaces 5. Braided cable Some cons: 1. Noisy button presses (not the noisiest, but if someone sleeps next to you at night, then this can interfere with him) 2. Little fingerprints remain on LMB / RMB (I use clean fingers))
