So they have to produce them and ship them at $2.82 per unit just the break even, not including their half dozen staff and all the money they have spent up until this point.
Good luck.
Rubbing in the salt?
Nope, just pointing out a common scenario that many of these crowd funding campaigns find themselves in. Successful, but not successful enough to actually make a profit, so unless they can get money from somewhere else, they will go out of business.
In reality though, Batteriser have a lot of money behind them from a VC company, hence their crazy low crowd funding goal. Their goal is clearly not to make money from this campaign (and that's good for them, because they won't make money), it's just a stepping stone to their grander plan.
Will be interesting to see how long it takes them to deliver.
And of course once they deliver a single unit, the technical world will be able to actually test it and verify it, which I'm sure they are not looking forward to. If they were looking forward to it then they would have already handed them out like candy to all their critics.
