 The Steel Series Aerox 5 Wireless is light, it looks good, glide on the pad is smooth, and it tracks movement well. So, how do I really not like it? Two points. First, sometimes it goes to sleep and just won't wake up. I move the mouse and nothing happens. No lights, no movement. I feel like I should tuck it into bed instead of having it beside my keyboard. Second, battery life is terrible. I've used wireless mice most of my life and I think this is the most I've ever had to constantly charge a mouse. It's also the most I've ever worried that it will just die on me in the middle of gameplay.
