I am a hard core gamer myself and like playing games specially on my personal computer and hence the mouse place a very important role for gaming, so I bought this mouse for my personal use and it requires a couple of AA batteries.
Costed around 400 bugs and is not a real cash in for money according to me, its slim and is delicate and once fallen down it becomes terrible and may not work again and also the stability is bit on a lower side too.So it cannot be recommended especially for hardcore gamers.
