Now dont get me wrong here. I really do like this trick.
I just don't like some of the subleties. The action of shaking the pen to get the desired result takes way longer than it should take. I believe this ruins the flow of the effect.
These pens are cumbersome to switch out. I like the concept but hate the design.
