Review on Art3D Activity Centers Children Different by Cody Michels

They look very cool and unless you have a kid who can pick individual tiles off the floor you'll probably be happy with them. I figured (due to the nature of liquid filled sensory items) they would be soft. You are not. They are very rigid with sharp corners. Aside from permanently mounting these tiles in a wooden frame, there's no real way to make them a safe addition to a sensory space for anyone curious enough (with the requisite fine motor skills) to pick them up and turn them over to see them to see how they work. They're not connected to each other, and while I'm sure they're very durable, the risk of injury is pretty high for anyone who isn't neurotypical. They probably would have been amazing for a neurotypical teenager or something, but they didn't work for us.
