Currently using Razer Lycosa mirror and Mamba combo.
Had no problems with the keyboard, i like the look and the feel. It is very shiny like an ipod, so it gets dirty with finger prints within 2 seconds of use. I dont mind this, and spend 5 mins cleaning once every week. This brings it back to its shiny glory! But i can see that this could be a turn off for some. I also dont wear a watch and imagine it would get pretty scratched up by one.
The Mamba is the best mouse i have ever used. At the time i bought it, it cost a lot more than it does now. At the time i was using a Razer copperhead. I had used my cousins deathadder and liked the shape. As the Mamba was more or less a wireless version it became the mouse i wanted. Well i talked myself into buying it, thinking its the one thing i use on my pc most except my monitor. Today and the day i got it i didnt regret purhasing it.
