After having been through several kickstarters*, I will offer one piece of advice:
The biggest "headache" campaigns are always the ones where they end up getting 1000%+ of their original goals.
These people were prepared to do a manageable production run of a few hundred units. The kickstarter would have let them get the run started without an out-of-pocket investment, and then they would do rewards fulfillment on their own. Instead, they're funded to 50x their original goal, which means 50x the management issues, 50x the warehousing of product, and 50x the packing and fulfillment. Instead of five cardboard boxes from China, they'll be getting a small shipping container. Since the design is done and the construction looks fairly straightforward, I'd expect that you'd get your stuff, but I'd bet folding money it's going to be delivered late. If you're not in a rush, go for it.
*Surviving veteran of the "Unspeakable Words" kickstarter that kicked off in May 2015 to re-print an already existing card game (playing cards and some cast plastic tokens). Here in 2018 some of the international backers are still awaiting delivery. And that's only one of several such disasters I've seen.
