Handle bar mirrors for Explore E+ 1

Curious if anyone has a good solution for a handle bar mounted mirror for the Explore E+ 1 GTS (which comes with the small bar ends) ?

I like the idea of a mirror which mounts at end of the handle bar but then I find I am making a lot of use of the bar ends during my commute to change hand positions and avoid numbing ... is there a clamp on mirror people are happy with ?
