As titled. I'm a trackball user, however I'm fed up with the fact that most mouse and trackball all have their left micro-switch break so easily. I'd like to think that I'm not a heavy clicker (I'd use controller whenever possible, and I don't do FPS game). My Kensington Trackball left micro-switch just went out, after having it for 8 months. Before that a Logitech wired trackball and M570, all died of faulty left micro-switch. So I'm looking for a mouse or a trackball that has durable micro-switch. Preferably trackball but given limited selection on trackball I'm open to regular mouse too. I could use MouseKey but given how inaccurate it is, it is not good enough.
