| Re: Optima Cartridge
A granular adapter is likely to result in a significantly shorter duration unless the housing were to be changed, which is lilely to interfere with the case, etc.
My biggest issue with the O2ptima is the cost of the cartridges. Its just flat-out excessive. 4 "fills" for $120ish is the going rate, and that's about double the cost of granular in most cannister designs.
