I have used this monitor for over a year now, and it is working great for me. It's small and can be tucked away near the dash within my line of sight.
I like the simplicity of the lights--if I'm seeing red, there may be a problem. You may see red when stopped at a corner, but green comes on when normally riding.
I'm really not interested in seeing detailed battery info, and this tells me basically when the battery is fading or electrical add-ons are too much. (Posted on 7/18/13)
