i nvr tried the gaming mouse by alienware

but if u wan i think can go also gua... try ask around the hardware zone.
for me, i would recommend razer cuz razer is a gaming company that focuses on their mouse production. the razer orochi would pair nicely with m11x since it is ultraportable like the m11x.
but i use razer mamba and all i can say is, its the best wireless gaming mouse. the only drawback is the battery capacity. for more info, go razerzone read

do some research before purchasing your rigs on your own so you'l appreciate it more when it comes ~ ^^ thats my personal experience. hehe. but anyways, for more info bout razer mouse can ask me or pm me. will try my best to answer.
