A review of the Herc X and Herc fidget spinner upgrade buttons I purchased from NeoSpin.
The Herc X is the R188 version. It has an “eXtended” height so it works with almost all R188 fidget spinners, including those with a collar (like the excellent We Fidget The Bar https://amzn.to/2qXFSVv ) and those without, like the TorqBar.
The Herc is the 608 version. It works with spinners like the Yardwerx Dab: https://www.youtube.com/watch?v=H6UOEZNNxT4
Overall, I like the build quality and the idea of these buttons but I do not enjoy using them. They are just too bulky for almost all my spinners and the knurling on the sides irritates my fingers. The one application where the Herc really works is on the larger Yardwerx 608 spinners, like the ill and Zik. I have no use for the R188 Herc X since I find it to be too big for almost all my R188 spinners.
