Pros: I can only imagine how difficult it was to come up with even ONE clever innovation for a mouse, and this mouse has three. The three major innovations in mouse design are: 1) The shift key you press and hold with your thumb works just like the shift key on your keyboard and changes all the buttons to do something else (almost doubling the number of programmable commands, except for the two thumb buttons... unless you have two thumbs of course). 2) The X-Axis thumb control is a very clever addition to the mouse. It is a solidly built paddle lots of potential for use with different game types. Plus you can fiddle with it while waiting impatiently for your server to load faster. 3) The 'fin' style paddle switch on the top of the mouse is a way to get fast access to two more buttons without moving your fingers too far from the main controls. I have large hands and tend to have an arc-grip on the mouse. I can only imagine how great it works if you have huge blubbery meathunk fingers with a flat-grip on the mouse... you'd hardly have to even twitch to activate it. Not innovations but great features: the buttons situated to the left and right of the main mouse buttons are of better placement than on other mice I have used in this category (like the Logitech G700). I never thought I would actually use those buttons to the top-side of the mouse, but I do now. Some people may think that no weighting system is a con, but personally I think its a pro. I think weights are a fiddly silly add-on for a mouse, try getting a nice gaming mousepad for a real difference. For the amount of tech in this mouse, its worth the $100. This it the expected price point for a mouse of this caliber.

Cons: I miss the two extra thumb buttons on the Logitech G700, this mouse only has two. I tried giving it a stern talking to no avail. Still a superior design overall. Also the Logitech G700's ability to "unlock" the scroll wheel was really neat, albeit rarely used. So rare in fact I forgot it even had that feature until I accidentally triggered it while trying to repair it and thought "oh riiight."

Overall Review: Software-Lights: Unlike some of the previous comments, the software is great. I admit I was thrown at first when my color options didn't seem to be working... maybe this little trick will help other people too. In the color effects the word "flow" means color-flowing from one color to the next. If you want the mouse to stick with 1 color you have to select "No Color Flow (off)" and the mouse will not change to random colors. So dont go with the flow. Its distracting. Software-Profiles: You can program each profile with its own light set so you can quickly change to the profile you need for the application you are using. I even have a whole profile for using this mouse at work... macros make me a much more efficient worker because I am lazy. I think I may buy a second one so I dont have to remember to bring it with me every day. I asked my work to buy me one but they laughed. I admit I cant figure out how to turn off a profile I'm not currently using, I just turned off the mouses lights on the profiles I'm not using and skip to one I use (clever right? Yes.) This mouse has 5 personalities and despite therapy refuses to admit it has a problem. On board memory: The On-Board memory means you can program the mouse on one computer and then transfer the mouse to any computer (even one without the driver software) and keep the macros and buttons you programmed (not a feature unique to this mouse, but one I like and use often). Its like comparing a dumb-phone to a smart-phone. This is a smart-phone-mouse. Except not a phone and with split personalities.

Pros: Nice color, fans are quiet and it stays cool.

Cons: I bought this case to build my dream gaming machine. My first real computer build from the ground up. At first, I thought this case was amazing, but when the actual building process began I quickly realized how terribly incontinent the case actually is. First case power supply should never be on the bottom - this is not how most are but this one is, and it means I have to literally stretch the CPU power across both of my GPU's and around the CPU fan itself. I cant take out either of my graphics card without unplugging the CPU power. Also, the cable management system made it very difficult for me to even put in the motherboard. I have an Nvidia 680i motherboard. If you want to "manage" your cables, do it yourself with some zip ties, the clip things dont come out of the case without a fight.

Overall Review: Just make sure to buy a full size case with a power supply hole on top, and no cable management system. Will make your life much easier. I say full size because it gives you room to hold a flashlight in there if you want to -- not easy with this case.
