Preview works, nothing beyond that. – View-Master® Destinations Review

You can view the preview, but if you try to buy the full set nothing happens. Since this is Mattel you can rest assured it will never be fixed in our life times. Note none of the positive reviews talk about downloading anything past the preview. I'm willing to bet they are all written by Mattel. This is hugely disappointing, but it explains why they never came out with other sets beyond the initial three.
