I think in the end it boils down to the question: Who manufactured the Cometa parts?
I though this flashlight should have been manufactured solely by Jax with the chance of less Manker QC drama.
Maybe I’m wrong, but the unasked last minute changes seem to indicate, that someone (Banggood?) tried in a hurry to incorporate the Kronos/Manker 17mm X6/X5 driver to save some money.
Generally it’s not bad to try not to reinvent the wheel, but these changes should have been done by somebody with more flashlight engineering experience (the risk of a short is a disaster) and approved by the Cometa team.
