Wow, i was half serious but did buy it from the IG ad, and 3 months later after seeing the ad over and over, notice the orignal creator kept tracking the scams and posting in the ad comments it was a scam, I reported it to paypal, and the day after that (roughly 2-3 months) they shipped it, and it was wack.... like parts of it seemed to be machined, but not the acutally thing from the video from the og prop maker.
It's difficult to second-guess a scammer but this could very well be something that started out like a scam with the intention of shipping nothing, but within 3 months turned into more like a Kickstarter where they got a bonanza of buyers beyond expectations and decided to build and ship some products after all.
At least ship to the wheels that squeak enough.
And only ship when product is available, it doesn't have to be a sustainable business if it was supposed to be fly-by-night to begin with. So they could quit any time, or keep going for quite some time even after "inventory" has been fully depleted.
Could be about the reverse of the Kickstarters that started out legitimate but end up the equivalent of a scam when they fail to deliver anything.
