I am very disappointed in flip dunk. It seems someone is bound to get hurt. There are 3 years olds jumping with 13 year olds. And the older kids don't seem to care at all if the little ones get bumped. They really need a better system to divide things up a bit. On top of that there is constant dodge ball going on which in turn an innocent person not even playing is bound to get chucked in the face with a ball. (It happened to my daughter). The staff will do nothing about it. Maybe because all they have is a bunch of 16 year olds supervising who basically stand their twiddling there thumbs and look desperate for their shift to be over. Bummed that it is the only place in central phx to go. Was thinking of signing my daughters up for gymnastics but now need to reconsider.
