Well, I would rather save up money for better and slightly more expensive ones for two reasons.

1. It's Kickstarter. You could wait dozens of months if not years and final product might be very different. This is especially true for these budget products made by inexperienced teams.
2. These machines are full of tradeoffs. They're using cheapest parts available. That means you WILL have problems and quality of printed parts will be low. Very bad when you're printing functional parts where you need good tolerances. Safety is a big concern too. They can literally burn down your house!

So save money for slightly more expensive printers, like Monoprice Select Mini: https://www.amazon.com/Monoprice-Select-Printer-Heated-Filament/dp/B01FL49VZE?psc=1&SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag=duckduckgo-ffab-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B01FL49VZE
