The 400k sales number given was an "indicative price" not an actual sales figure, is it realistic or complete pie in the sky stuff no one knows unfortunately. With regards to wether or not to offload it honestly depends on your point of view and situation but I don't think many at the moment would feel comfortable holding shares if it's money that can't afford to lose.

Best case scenario is physical production is further along than we realise (unlikely) with the app pretty much done and in testing (unlikely) als0 the sales number given is a good as sorted deal for half a million units (unlikely) and they can produce large numbers before Christmas (unlikely). If all that does come to fruition they have a chance at a successful launch if any one part of that fails they probably bleed out for another 6 months before walking away half a million dollars richer and with basically nothing for shareholders.

Your better off pulling out and placing it on a hand of black jack instead but thats my opinion of course and I advise you to DYOR.
