It is bigger than I expected. Came very fast. Does its job. A small imperfection which does not affect functionality.

Corresponds to the description, I recommend the seller. Arrived in my country quickly. Good article looking forward to tester it

Great balls for mfr. The best I tried, light but hard.

Very light, they look like feather, but they do their function, good massager

The single ball is great for massaging upper back against the wall. Provides relief from back pain where you can't reach with hands. Peanut ball is great for calf massage. For use on back massage, it can be quite painful.
