When Logitech started their G Pro Gaming line with a mouse, I found it to be a simplistic but efficient device that would work well for eSports. Well, at least, I think it would. I'm not good enough for tournaments. I'm happy just to finish a match in any game without someone yelling at me about how I'm a shitstain on this Earth and I don't even deserve to play.
Logitech now has a tenkeyless keyboard specifically designed for eSports, which I'm going to pretend I am qualified enough to judge.
