Input: We always have a blast with these during any public holiday Fireworks displays with our grandkids and any other kids at the parks. As we see other kids come by we offer them to let the balloons fly. Kids have a blast with these and surprised when we offer. The only issue is that these tend to pop a lot. within about 2 hours, we probably had 15 balloons popped. also, some seemed to have smaller openings or are difficult to insert the pump into them. However, still worth fun it provides for all the kids.
