As I expected, not heat stable enough!
I had been wanting a stainless version to test out a new idea i had, and so the kickstarter was happy info... but sadly not yet to be had.
Still, nice to see one comming to to the market, but a design that one could make one's self would really be nicer.
I'll check out the diy pages (again) just in case there are auto-siphons described now.
