Razer Tartarus Chroma Review @ Vortez
 

The Tartarus is an ergonomically designed keypad with 25 keys at your fingertips with a further alt key and space bar straddling an 8 way thumb pad. You can instantly switch between 8 key maps, save unlimited profiles and unlimited macro lengths to the 25 fully programmable, full anti-ghosting keys. With all this taken into account, it is easy to see how in the Tartarus can become a highly versatile tool in the right hands.
