sogman I have been a paying user for two or three months. If the free samples still make you curious for more, I think it's worth paying for one month since it's only like 5-10 bucks. One month will be enough to explore all the content.
The reason I finally decided to cancel was that content updates are rare. I think what you can expect at best is like one new 'scene' per week with a duration of a few minutes.
Image quality-wise, I thought it was quite okay considering the early state and limited resources behind it. What bugged me more was the app which can be a pain to handle, but it's working. Another thing I noticed was that performers never seem to look you in the eyes. Would be so much better if they did.
An unsolved problem of this tech which also occurred in what Naughty America was doing is open mouths. It seems to be a problem to properly scan body cavities and faces with open mouths look a bit weird.
What's definitely a great experience is to get an idea of how it would be to walk into a scene and become part of it. If they had a huge content library, I would have definitely stayed for longer.
