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 Nguyn Qu Thnh (Lo Lo ᠌

I've been using the mouse for a little over a year now. Duracell batteries last for 2 months of daily use. For half a year there were no double clicks, the wheel works great, but the sensitivity of the cursor and software is a problem. 1. Randomly (uncontrollably) the surface calibration setting in Razer Synapse flies. I tried to reinstall the software, tried to connect it to another computer, the results are the same - the settings are lost. As a result, the mouse cursor starts to work differently than it was configured. Most likely, the settings fly off at the moment of disconnecting and connecting the mouse. 2. Stably every day, the mouse may not wake up from sleep mode. You have to turn on / off the toggle switch at the bottom of the device. Is it difficult to do this? No, but why? ) Probably, this is all a consequence of the low cost of the mouse. Would I buy this mouse again? No. I will buy other options. I do not recommend to buy.
