General Thoughts

Razer's entry into the light-weight mouse market is amazing. They managed to reach about 70 grams without holes all over the shell on a medium fingertip grip mouse. Not only that, they really went next level on the features: 3390 top optical sensor, on board memory that will remember everything except macros (competition reasons) so you don't need to keep the software installed, full ambidextrous design so you can use it left or right handed and use buttons on both sides, which also means you can make use of the Hyper-Shift functionality (bind a button that when pressed will change the function of all the other buttons, almost doubling the amount of commands you can have on the mouse), super light weight, soft, smooth flexible cable and so much more. Even the rubberized grips are some kind of blend so the rubber is combined with the plastic, meaning they can't fall off without the whole panel falling off. It's also really well built, especially considering its weight. Have to mention the optical switches too, super low latency and should avoid the double click issue on regular switches. There is so much to love about this mouse, I could go on and on and on about it. But watch the review for details! On a personal note, as an old school Razer fan, I'm really happy to see them back in the "top FPS mouse" game. I was a big fan of the Diamondback and Copperhead shapes but this is one of the best I've ever used.
