​ I use two.

The one on the left is good at clicking but bad at dragging, while the one on the right is good at dragging but bad at clicking. I’ll switch between the two moment-to-moment depending on what I’m doing at that time.

I got the green one from my sister cos they both work fine for the most part, and together they emulate one perfectly working mouse.

I use a controller for games so why waste money on a new one when this works fine?
