I had a corded keyboard by Azio that was very similar to this but I needed a cordless. This one is absolutely perfect, it shuts off to save the charge and after 1 solid week of use it still doesn't need charged. Awesome keyboard!
So far so good. Of course there are improvements that could be made. Aside from some MS Control Panel settings, I see no way of adjusting anything. For instance, the volume control works only when the Mixer panel is raised. Also would like to vary the back light timer/ e.g., make it last longer and varying back light color and intensity. I'll probably learn more or have additional comments as I use it more.
