Review on Razer Basilisk Ultimate Hyperspeed Wireless Gaming Mouse with Charging Dock: Fastest Gaming Mouse Switch - 20K DPI Optical Sensor - Chroma RGB - 11 Programmable Buttons - 100 Hour Battery - Classic Black by Ada Kuakowska ᠌

Its pros: Without wire. The wires got messed up. It works better than many wired mice. The whole office bought these for themselves to cut into CS during breaks. It sits very well in the hand. Batteries need to be changed about once every 1-2 months. Some cons: A year later, on one mouse, the left button began to lag. They thought because that mouse was often dropped and poured with soup. But about a month later, the left button of the mouse was laid on the other mouse, although now no one dropped it and did not fill it with anything. Seems like a problem for the entire series. The third mouse works as it did, no complaints. In general, I liked the mice, although they are very expensive. To replace the first, they already took the fourth.
