Tbh I only bought this trackball because it was super cheap, and I wanted to evaluate if I could get used to a trackball. I can check the brand/model when I get home, but it’s a thumb-ball. Main nice feature with it is that it supports both bluetooth and usb wireless.

I’d like to try a fingerball as well sometimes, I find thumb ball plenty useable, but I don’t think I could do nearly as well at FPS games with it vs a traditional mouse (I might just need more learning time though). I think a fingerball might be better for me.
