But if in the description it says "activated" Then it probably is.
You can try Core3 crack for newer mouse (TL8/ZL5 etc) but idk if the keygen works or not as of now.
Core4 is for MMO dota etc (not this thread)
Core3 is for FPS games (BF4)
This one is activated: Amazon.com: A4Tech Bloody V7-PRO/Activated Multi-Core Gun3 Gaming Mouse (Wired, USB): Video Games
But I recommend to wait for newer models of A4Tech bloody (the wireless RT5 looks nice)
