First of all, hello Bruce and welcome to the forum, nice to have you here! I’d like to put my ideas on your mask here based on what I heared so far, perhaps it might be useful to you.
Ok, so this is a nice test. 50% of subjects got at least one LD during 2 weeks! But according to me (and probably many others here on the forum), if you would put together another group of these students, who dont know anything about LDing, and you would teach them certain well known methods to induce LD’s (like WBTB + MILD, which works for a lot of starters very quickly!), my bet is that you could get at least the same result. Granted, one would have to put real effort into it, but this effort would be well worth the result and would not cost anyone 400 dollar (if that is really the price, I would never spend such a huge amount on such a device).
My conclusion sofar would be (and I dont want to offend you personally, this is aimed purely at the product and price), that your tool is a nice gadget for rich people who are too lazy to invest serious effort into learning to expand their nightly endeavours, or for those who wish to try and test a gadget besides their current induction techniques, that might (or might not) help them to gain lucidity and are willing to pay big time for it. Also it might be helpful for people who lack the time to LD seriously, perhaps fot those with a bizzy job schedule and not a lot of sleep. I could see how this could be useful to such people if you were to keep working on the dream maker to make it even more succesful.
