It turns a little bit tight right out of the box, but after a few turns, becomes better. It's not super hard at all, what makes it really enjoyable to play. The quality impression is great and the colors are easy to distinguish, nothing to worry about. Definitely buying another puzzles!
Thank you so much for the detailed feedback and the stunning photo of the C4U Rainbow Arecibo!
You’re absolutely right—since this puzzle has a complex internal structure, it can feel a bit 'tight' initially, but it definitely becomes smoother after a few solves (the 'break-in' period). We’re thrilled that the vibrant colors and build quality impressed you.
It looks amazing in your collection! We look forward to seeing what your next challenge will be.
Best regards,
