Rated 5 out of 5★ by theRealBrynczka Great lightweight gaming mouse A little background for comparison: I'm a desktop PC gamer. Before buying the Razer Orochi, I used a stock HP computer mouse, along with a portable Microsoft laptop mouse, interchangeably. The problems I had with the stock mouse was that, for one, it felt too big for my rather small hands; and two, the wire constantly interfered with my desk's sliding keyboard compartment, often getting in the way of my desired motions. Switching to the Microsoft wireless mouse, I was much happier with the size and comfort, but the scroll wheel would often break, its paint would often wear off, the general condition of the mouse would quickly deteriorate, and, of course, it only had two buttons--I wanted more to bind a few quick-use actions to (for multiple games such as League of Legends and Fallout, to name a couple) easily useable mouse buttons.Thus, I wanted a wireless mouse that ergonomically fit my desires, had a few extra buttons that wouldn't be bothersome, and wasn't too expensive. First of all, if this matches your criteria as well, let me tell you: there aren't many choices. Nonetheless, after buying the Razer Orochi, I realized my criteria was slightly off; I didn't need the mouse to be wireless at all. (Razer mouses tend to have cords/wires of amazing quality, and the Orochi is no exception.) I expected to use the wireless mode more often so that there wouldn't be any cord tugging on the wooden edge of my desk; however, the Orochi's braided cord seamlessly slides over almost any surface without any hint of damage or obstruction. Additionally, the quality of the mouse itself just feels... fantastic. I'm no expert on material of which mouses are made, but I absolutely love the feel of the Orochi; sometimes I'll just grip the mouse because of how nice it feels. And its paint and Razer graphic show no signs of deterioration whatsoever. The mouse is great, lightweight, and as accurate as you could expect. Oh, and the four additional side-buttons (two on each side) are quite comfortable and easy to use as well. One thing I found to be pretty awesome about them is that the two buttons on the right side, by default, adjust the sensitivity of the mouse pointer, so you can alter it at any time you'd like--even in-game. Just as well, you can bind the four side-buttons to any action you desire.So, key positive points and "TL;DR" version:-very lightweight (.15 pounds)-interchangeably wired or wireless-high quality-quite small--probably smaller than you'd assume based off the pictures-very high-quality cord for wired mode; I couldn't recommend it enough-efficient 4 extra buttons, 2 on each side (easily click-able with thumb and pinkie)It does have one small negative for me, however:-Wireless functionality is achieved via Bluetooth 3.0. My desktop computer does not have Bluetooth by default (I'd have to buy a USB Bluetooth dongle to use its wireless mode, which is pretty cheap if you're in the same situation and are considering one). I don't see why Razer didn't go with the standard USB wireless functionality, but to each their own I suppose. And since I haven't used it in wireless mode, I cannot comment about its wireless performance.I hope this review helps anyone considering a small, comfortable, high-quality gaming mouse. 10/21/2013
