I eagerly bought two packets of the initial release. None of those pictures survive today - The either faded instantly, and then once I had figured out they needed to be shielded from light as they emerge, subsequent pictures were destroyed by an interesting crystal growth. Kind of entertaining, mostly just annoying/expensive. Two years ago, I visited their shop in Vienna, and left without buying anything, which is not my normal camera shop practice. Subsequent improvements to the technology have not left me brimming with confidence. I really wish their product was any good - I would actually buy some.
