Review from germany:
I saw those puzzles by accident on imgur and I instantly felt some curiousity due to their strange unusual look. I bought them and couldn't be happier. They are interesting, hard, and its fulfilling to finish one of those.
One thing I have to mention: I got 2 Emails from this website, asking for a review, before the puzzles had even arrived. I would recommend to change that a bit, so when puzzles get sent overseas, the website waits a bit longer.
