Crowdfunded projects are risky definition, because you're financially backing something, not merely purchasing an item.
But I don't think that's necessarily something to be scared of - just be cautious. And with that in mind, whenever you see a crowdfunded project by a **company**, run away, because it means they're not risking their own money.
Just compare this sorry Vega+ tale to the ZX Spectrum Next. Yes, it's running late, but the first stage of developer boards went out. There's been regular monthly updates from the team which actually detail and show photos of the production process and how it's going. And the team is made up of passionate people who actually care about what they're doing, and are doing it not-for-profit. There's no shareholders and directors siphoning off money and bickering with each other. And the community of backers are actively involved - helping out with documentation, OS and firmware, writing emulators and games for it..
