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 Kenta Kajikawa ᠌

A day after use, in games it began to fall off, through the dongle (the speed of movement and keystrokes gradually decrease, it does not respond to the dpi switch button). Through the bluetooth during the game, a dead zone appears and sometimes the reaction disappears when pressed. Moreover, it behaves differently in different games, but it starts with a feeling of a micro-intermittent connection. ated firmware, didn't help. The technopark store sent it to the service, without the possibility of replacing or buying a more expensive model, citing the loss of its presentation (there were grooves on the pads of contact with the mat for 2a in the evening of the game !). There are more questions for the manufacturer than for the seller, BUT keep in mind this is the moment that even a defect identified in a couple of days after purchase can be left without a mouse. 06202222: replaced under warranty. DeathAdder 2 pro is better and worth it.
