It may be one of the biggest crowdfunding sites, but these are notorious for being used by scammer vaporware salesmen. I.e. they promise extraordinary products and never ship, and there's nothing you can do about it, because legally you're not a 'buyer', but just a 'backer' of a project who gets a 'reward' for your generous donation, in case the project succeeds.
This failed many times with 3D printer projects about half a decade ago and backers never got their printers.

I don't personally agree with big companies selling products via crowdfunding websites, because they are essentially just offloading their risk (of not being able to deliver) to buyers instead of taking it on themselves, while they clearly could.

That being said, you can trust such a company much more than a brand-new start-up to actually deliver and send you your 'reward'.
