Just to be clear, again, these PICO Lites that Mike is selling are from a pre-production run and the production lights will have a number of tweaks, including a better means of loading replacement batteries and a more compact, more robust, and nicer looking clip, as well as a few other very minor changes that will not really be noticeable to most folks. OTOH, these first PICO Lites may be collector's items someday.
The production PICO Lites are at least a month away, perhaps two.
