Someone keeps posting a link in the comments to an AliExpress product that looks nearly identical (except the colour, and sold without battery).
I love that video snippet of them attempting to tin some stranded wire, and totally failing.
Edit:
Adding the AliExpress product link here for reference. Not something I'd recommend as it looks pretty poor quality and underpowered.
https://www.aliexpress.us/item/3256805809166061.htmlI also reported the project to Kickstarter, but I think it is too late for them to do anything.
The creator insists theirs is a better product, and has probably already been questioned by Kickstarter staff.
It is pretty common in China that several factories in the same region will all make slightly different versions of essentially the same devices, just with slightly different specs as they tweak it for their own manufacturing processes, parts sourcing, and cost reductions.
