Perfect for teachers
I had a single foot pedal to use for PowerPoint presentations for lectures and it worked great, but if a student had a question about a previous slide, a single foot pedal couldn't go back a slide. It wound up feeling moot to have a foot pedal when I'd have to constantly go to my computer to go back a slide again and again. I did some research and found this double button pedal and it solves that problem to a T. I'd really recommend this to any teachers going through PowerPoint slides daily because it's way easier to keep focused on the lecture rather than having to work with your laptop to make PowerPoint function the way you need it to.
