I love this item so much. Definitely one of my top Amazon purchases and I’ve bought hundreds of items here. It’s also one of my top sensory toys, and I have probably 50+.The clanking sound this makes is perfect, not too high pitched or too loud, just right. It also wriggles in your hand so nicely, it’s almost like a slinky. It’s made very well and seems very durable, I’ve had it for a few weeks now and no issues. 3D printing quality is great, trimmed nicely without any jagged edges, frays, or faults. Gift worthy and seems durable.This thing is fun even for an adult. Where was this my whole life? An expensive but fun toy for both kids and adults who like to stim.I like playing with this more than I expected. I needed something to keep my hands occupied while on calls and thought this is cute and would be fine. But it's even more enjoyable to toy with than I expected. It feels kinda squirmy and is so much better than more basic stress balls or fidget toys.
