A good ball

I have been using the balls that came with my new robot because they feel harder and when you try to press into them, its less indentation.  This could also be because they are meant to last through the machine.  Is it ok if I have a 3 star ball and I can indent it a bit but it comes back out?

Hi Bennett,

If you press on the ball and it pushes in and then comes out again, they are probably too soft and not worth using.
