Fantastic set. I haven't used fidgets before and this kit was a great way to try different styles. I really like the chain and the cog, and I'm getting a lot of use from the centipede. These have helped me focus in meetings, avoid picking my nails, and prevented me from absent-mindedly getting ink all over my hands from twirling my pen. I am also surprised by how much I like the sensation of the spikey - I never would have bought it on its own, so I am very glad the kit gave me the opportunity to try it. The components are all good quality and well presented.
