Pros below: The mouse is comfortable to use. It is quite suitable for a measured game of MOORPG. For my hand, the side buttons are located well. Simple and understandable software with the ability to install scripts on buttons. Got cons: Reliability. After six months of use, periodic problems began with incorrect operation of the mouse wheel when scrolling. Not critical yet, but for a gaming mouse, from a well-known brand, I expected a longer service life.
