Got this for my wife's bike for our coast to coast and TAT ride this summer. Since there aren't very many choices, I guess this one is as good as any. The knobs are very stiff and you have to loosen the roll with the top knob before you advance it or the paper will tear. Also, the wingnut holding the whole thing together vibrated off the second day. Stopped at a hardware store and got a replacement, put a piece of electrical tape on the end of the bolt to prevent it from happening again. Loading it is kind of a pain, but they are all that way. Thankful I have GPS and roll charts are fading away!
