Bought G500 in return absolutely satisfied Pros below: Compare with G500. The software allows you to adjust the change step and DPI level. The forward and backward buttons are conveniently located. The inertial scroll button is a necessary mouse functionality for me. The shape of the mouse has become more comfortable under my hand. The software allows you to turn off the backlight. Feels fine on a table without a rug. Weights used all. For me, they are better. Cons: I'm afraid to get a hernia on the wire winding. For the G500, this was a problem. The clicks were loud. The customizable button on the left edge is habitually set to turn off the sound, but is located less conveniently.
