Genius DX-110 muis Ambidextrous USB Type-A Optisch 1000 DPI

absolute rubbish, have to click up to 3 times for it to work and courser jumps from one side of the screen to the other by itself regularly.

This is much smaller than the average mouse and more suitable for children

decent mouse, but give it a pass if you have large hands. If rest my fingers on the buttons, the palm of my hand doesn't touch the mouse which is not very comfortable. Other than that, performance wise, it's a cheap optical mouse that does exactly what it says on the tin and nothing more.
