I bought one of these in the pandemic, used it a bit then let it gather dust. After seeing a friend using theirs on Insta, I got mine back out earlier this year and got obsessed. It's the soberest high I can possibly feel. It's so good for those moments where you feel all frantic and would otherwise reach for snacks/stimulants, replacing one intense feeling with another really relaxing one. I think I'm close to graduating from the starter mat to the big-boy spikes. Even my sceptical friends have ended up loving it.
