It doesn't work as advertised. It's complicated to put together when no instructions come with the product. It also just, doesn't work. The ball doesn't move around as advertised. Even after youtubing and googling how to use the product it still doesn't work. It's also advertised as made in/shipped from the US and the product took longer than expected to arrive, and was shipped from China.
Can’t get the ball to keep going around, I’ve asked others and watched videos saying to do all the little tricks to it, still won’t do it. Also, mine seems shorter than others.
It is really difficult to use.
It didn’t do it for me it honestly just overall sucked
