Its worth it for its looks and all of the functions etc, but i wouldnt pay that much when you could spend 25-30 on another mouse that would perform almost as well if not on par, except you may not have as many buttons, unless of course you have money to burn then go for it!
I dont do that much gaming but when i play Hitman or Doom3 i use my 30 quid packard bell wireless/infa-red/rechargable jobbie works fine and it has the usual 2 buttons, centre scrool wheel, hotkey for putting certain funtions on to it, and also back/forward buttons for your web browser, and it lasts 2 weeks once charged and thats using it every day
I took a pic because im bored
Had it about 6months, flawless
