This difference in diameters is really the only difference that I noticed among all of the toning balls. They are all made of soft vinyl, filled with sand and air, and a great alternative to the tranditional hand weights. You can't go wrong buying the Valeo, GoFit or Danskin weighted toning balls.
UPDATED (4/17/06): After using the toning balls for several months, I have found that I actually prefer neoprene dumbbells. Dumbbells are easier and more comfortable to hold and handle. I still think these are good toning balls. But given a choice between a toning ball and a neoprene dumbbell, I would choose a neoprene dumbbell.
