You're opninion is even more promising than mine! But i was, as stated, already very conservative! I appreciate you're statements, and keep them in mind for my future strategy! But you were also correct by stating it is still to early, is 100$/unit a good estimation? (i also don't know, but just a personnal guess) ... Single cavity or multiple cavity will have a different production cost... My 40% was by expenses related to UL-testing, design first, wages (Andrew, Robert and Richard), assuming that Gavin and others produce it themself! But i have a feeling, we are on the right track!
