maxim mini moxa torch: on the outside it says Tai Yi brand. is there a manufacturer website, with instructions, how to refill by way of the + or - opening at the base? this is better than the maxim torch (not currently in stock it says) pictured on goldenneedle, but a web search yields no website for "tai yi butane moxa torch" information

Thank you so much for asking. We have inquired from experienced users of this product, and find that the +and - symbols are indicators for which way to turn a small screwdriver, inserted into that opening to adjust the flame length. That same opening will accept a butane recharging canister tube for recharging. Hold the canister upside down and press the tube into the torch opening. if any other users of this product have tips, please add to this discussion.
