4 side buttons, 2 on each side (configurable). The mouse works well for both right-handers and left-handers. Different pros: Very cute and inexpensive. Works great. The software is convenient - the settings are not complicated. There is a backlight. Works fine without software. Cons below: No. Note: compared to the previous one, the buttons are slightly tighter - but this could be better.
To give a better sense of my experience, I've included some pictures.
