Review on Razer Naga Pro Wireless Gaming Mouse: Interchangeable Side Plates with Multiple Button Configurations, Focus+ 20K DPI Optical Sensor, Fastest Gaming Mouse Switch, Chroma RGB Lighting - Shop Now! by Hien Quang ᠌

There are some nuances with the Synapse software. the mouse and keypads are highly dependent on it, because, unlike Logitech, the internal memory is not used for profiles, only for the current one, and then it refers to the software. This situation gave rise, earlier, to sticking of buttons (not mechanical - there are good switches here) at the software level. Now Synapse is not buggy and there is nothing to complain about, but there is no guarantee whether this will always be the case (the last mouse had to be handed over because of this).
