but feels just a tad on the delicate side. I don't think it would take too many knocks, hence only 4 stars.
The size is good, small enough to be discrete but big enough to do the job once you get used to the image and the distorted perception of distance. I have straight bars and have mine fitted to the end of the offside bar end. For me it doesn't interfere with my hand positions and gives me a good view behind. Now that I am used to it, I don't think I would like to ride without it.
