Somewhere in this thread someone posted a Prestige Harvester combine they did that was arguably bigger.
The PR on this project was horrible. Its not just it was US only. They Crowdfunded on their own site, so no one came to know about it simply because they were on a major crowdfunding platform. (MST3K S14 is running now on their own site, and while its ticking along, it would probably be funded by onow on a big platform- getting the word out is key. ) I know of only one interview they did with a "you tube influencer", they didn't reveal or pitch this at comic con - or even a Trek specific convention that I know of. I believe they did just the one show in Chicago. And they advertised on Facebook of all places ( that worked to find me.. but if I hadn't seen the TOMY and known who they were I would have skipped over it as a scam) I don't think it was lack of interest, it was lack of reach to the people would would have been interested. Which is why you see the ones selling on ebay for between 1200-1400 on average. If the market had been saturated, people would be sitting there with thier own , and 1-2 others unable to sell them. If TOMY had set up interviews with all of the bigger adult Toy collector channels, or entertainment channels like Nerdrotic, revealed the thing at Comic-con SD, paid for commercials to run during streamed episodes of TOS, directly contacted Mods at the more prominent Star Trek Forums and groups, and so forth... they would have reached that 5000 goal and more.
