I recently bought Steelseries Sensei + Steelseries 4HD mousepad and cant say nothing. I didnt want the razer mouse bcse if u wanna gaming mouse i prefer simple design, which razer has not. Its so smooth and comfortable and you can set up all the shit, also works perfectly for shooters like CoD. Only the buttons on the side is not so well placed so i use them for quick buy and that shit. Anyway for keyboard i use Razer Arctosa and its great too. Gonna upgrade to Lycosa bcse i want the light on it. So i can recommend these for anyone who doesnt know what to buy. ;)
