Mini Simmons sizing

Does anyone have any experiences with Mini Simmons? One popped up in my neighborhood and it's very cheap but I'm also wondering whether I could make it work.

Any ideas on the sizing of those?

And no would it definitely would be my go to regular board, but I think the fun factor might be very high.

Does anyone remember that pyramid of progression video? It's from quite a while back. Can't find it. Would appreciate someone painting me in the right direction.
