Pros: 1) The keys have a backlight for night time gaming. 2) 18 extra keys on the left, with media keys and an LCD screen at the top. It has previous, next, stop, play/pause, and mute. 3) Switch for turning the WinKey on and off. In games, if you push the WinKey, it exits the game, letting you lose. When it's turned off, you can push it all you want and it won't do a thing. 4) Has 2 extra USB ports. They don't supply much power, but they do power my mouse (I only have 2 USB ports in my laptop).
Cons: None, except you have to know how to use the software. If you can't figure that out, it will seem like it's broken.
Overall Review: I didn't buy it at Newegg. I hadn't even heard of Newegg at the time.
Pros: 1) The software that comes with it is awesome. It lets you customize the buttons with a TON of options. 2) The left and right side buttons are good for web browsing. 3) Good shape. I enjoy a mouse that has a higher sitting. I don't like flat mice. 4) When scrolling, you can tell that you're scrolling. It's not smooth. That's good for gaming. You know when you switch weapons. It's not a guessing matter.
Cons: 1) The side buttons on mine were loose. I am able to jiggle them quite well. I don't know how common that is, but they were. 2) The side buttons are a little small. I have to move my fingers up to push them. 3) It collects oils from your fingers. I have to wipe mine off about once a month.
Overall Review: I didn't get mine from Newegg. I didn't even know of Newegg when I got it. I was just getting an external mouse for my laptop (a touchpad doesn't do well with gaming).
Pros: Great for browsing the internet and downloading things. No driver needed in Windows. It's just Plug-and-Play. I got the same 40 download, 20 upload speeds that my motherboard's built-in NIC gave me. Is able to stream 1080p from YouTube easily, assuming YouTube isn't having any trouble at the time.
Cons: The Mac OS X driver off of Asus' website doesn't work very well. It takes OS X about 30 seconds before I can browse the internet using that card. The card doesn't work well for gaming. It gives good pings, but I kept being teleported around in maps, regardless of which game and which server I played in. I'm not sure if this is the card's fault or a simple fact of the PCI bus. PCI can't send and receive data at the same time. It has to very rapidly take turns switching between those 2 actions.
Overall Review: I bought this card because my motherboard's built-in NIC died. I can't say anything about how long this card lasts because I've only owned it about 4 days.
