The mouse is really really good. The wireless technology is amazing. The Laser Sensor is the next thing to talk about, when you're viewing reviews, you hear so much about this sensor (that's so horrible) but I have to say that it's pretty good anyway. Certainly an optical is a bit better, think this sensor is perfect except that it does not track when you move the giant slowly as an optical would have done, otherwise it's very good. Personally, I do not care about it, do not think anyone else would make it pour, but it is remarkable. Have been running the Razer Lancehead Tournament Edition for 1 and a half years with an optical sensor and I can determine that the difference is very small and you will not respond to the sensor if you buy this - even if I personally prefer the optical variant because it is a bit better simply, but it is hardly remarkable. But the sensor is better than the sensor better than Steelseries Rival 300 for CS: GO, according to me, gives you more control and faster shooting. The mouse is so good, so it's totally sick, prefer the surface of this than the Tournament Edition, but both are good. The scroll is the best available and can not be compared to a Rival 300 ex. The weight could have been a little easier, or I do not know I get very good frag with the one it is. However, it weighs more on the back than the front. Razer Synapse is absolutely amazing. The mouse is really nice, Chroman is so handsome almost fancier than Mamba. Wireless technology is also very good. There is basically no difference in how the mouse performs even if you choose to drive it. You can also load it while driving. Recommend to drive it on a Goliathus Speed mouse pad, myself I run Extended Chroma which works great. In conclusion, I recommend this mouse to you who want a high performance mouse for all forms of gaming, perfect mouse for CS: GO and other similar FPS games and also perfect for other more casual games.
