That may well be someone who ordered a bunch with the intention to resell them in some sort of retail store. They may have absolutely no intention of using them or even trying them out, just to try to sell them to suckers and make a buck.
They may well have got them earlier than others because it was one of the larger orders which would have been shipped out differently and separate from the bulk of backers' orders. I will not be surprised at all if people really do start receiving them.
I expect that photo is genuine. That does look to be about what I would expect the real, finished, packaged product to look like. It is just still amazing that it is the first such photo that we've seen.
Didn't they lose the right to say Batteriser?
Their deal(s) with Energizer may well have allowed them to ship their existing stock to the IGG backers.
Without being able to see the agreement(s) or be a fly on the wall during their discussions, only the Batteroo insiders know what the precise terms of the agreement(s) are.
