Re: Bah!
There's also the fact that the backers are, generally, unqualified to judge the viability of the item being produced, for every Pebble watch there were hoards of Skarp laser razor, gravity lights, magic water bottles or solar roadways.
It just seems that far too many projects are led by designers who take one concept that they barely understand then produce shiny demo videos while assuming that everything else is a trivial engineering problem.
The other problem is the project team having limited business acumen, which is what this one looks like, so they fumble pretty much everything (good round-up here > https://www.youtube.com/watch?v=UkvOlE8qDB0&t=3s It doesn't look like they started off wanting to scam people, but the bad design decisions & infighting just took them further and further away from producing anything useful
