They are incredibly cool models, and really interesting/challenging to paint (they are detailed, and a lot of the detail is very fine). It was one of their biggest ever Kickstarter campaigns, although I only became aware of it after going through the history of their various campaigns after backing the latest Zombicide (that will be a big project when it arrives).
Up next from the painting table is the Koi Clan, much brighter and more vibrant than the Turtle Clan, so a very different clan to paint:
