Good quality. Easy and it doesn't take long for the motion to become smoother with use. I enjoy it for the absent mindedly fidgeting while watching something or listening to recorded lectures.

Sensory bags and panels like these are great for on the go. I carry similar items for my toddler because she is easily overwhelmed when we go places and it lets her redirect her energy or focus as she needs.
