Review on Logitech G G603 Lightspeed Wireless Gaming Mouse, Black by Michal Cedronski ᠌

I specifically took a model that runs on removable AA batteries, so that the discharged ones can be charged, and instead of them, immediately insert previously charged ones without resorting to charging by wire, as is implemented in the G403 and G703 models with a built-in battery. For some, this format is a minus, for me it is a definite plus. Its pros: In the hand like a glove. Although this is a subjective criterion, I want to note that for a large hand this is an excellent mouse. Excellent quality materials and assembly. It feels like you are holding a premium product. Two modes of operation - economy and gaming, thanks to switching between them, you can get the maximum signal transfer rate in games and save battery at other times. Before this mouse, I used the G700 for about five years, in which I changed the batteries every 4-5 days (although it worked on one AA-cell, and this model on two), but here it has been living on one charge for more than a month (in games on I rarely play a computer, the mouse is constantly in economy mode). Cons below: After the G700, there are not enough side buttons, on which I hang system commands - show the desktop, mission control, show windows of the active application, etc. But two side buttons are already good.
