BE CAREFUL
There's new fake NES classics and Famicom minis being sold on aliexpress, these aren't low quality bootlegs like the ones mentioned in the thread, these are faithful replicas running the same software. All the plastic molding looks exactly the same, even the logo and information at the bottom of the consoles.
I don't know if it's ok to post links to them but you can easily find them by the names in the listings:
"New Professional System For NES Classic TV Video Game Console Mini Version Built-in 30 Games Free Gamepad Gaming Controller Gift"
"New Japanese Console For NES MINI For Nintendo Classic Mini Family Computer Video Game Console Original"
"New Japanese Console For Nintendo Classic Mini Family Computer Video Game Console Original"
Right now the NES classic replica is going for around $70 and the famicom mini replicas are going for around $150 (why??? you can get the original for cheaper)
Prices will probably get lower with time and I'm pretty sure people will start selling them on ebay as originals so be careful.
There's a video from the manufacturer here
EDIT: I think the famicom mini is the original being resold on aliexpress, that's why it's so expensive. In the video comments the manufacturer of the NES Classic clone says the famicom mini clone will be ready in august
