The new Black V2 has the high quality OMRON switches common to gaming mice and has been upgraded to use an AVAGO laser sensor which allows you to increment your sensitivity in 100DPI increments up to 5700 DPI.  It sports 7 programmable buttons all of which can be set to send macros, a total of 35 programmable macros across 5 profiles using the included software.  The LEDs which illuminate the logo and indicate the current DPI sensitivity level can be turned on or off and apparently will change depending on how fast you are clicking if you enable Battle Mode.  Five 4.5g weights allow you to modify how the mouse feels in your hand, not a bad set of features for a mouse under $60Check out Mad Shrimps' full review to see what they thought of the Black V2.

"During our time with the Black V2, the product seemed quite responsive and comfortable, while the extra buttons can be accessed easily when in-game. The mouse was tested in multiple game genres and here we could count League of Legends, Echo of Soul, The Talos Principle, Serious Sam BFE but also GTA V; thanks to the new AVAGO sensor, the experience was accurate and if we feel that the default DPI steps are not for us in the current game, we can easily reconfigure them from the supplied application."
