I haven't had time to take pics yet, and maybe you're all sick of this thread (
) but the 8 hour paraffin cells are a slam-dunk, home-run-ball with the Mini! It's incredibly well designed, probably accidentally, for this purpose. As an added bonus the plastic tube it's packaged in fits perfectly in a padded cozy (w/drawstring) that I happened to have.
Still, for those who are interested I'll try to snap some pics of all the products mentioned.
