No complaints. Delivered deflated (normal) and I left a few hours at room temperature inside before inflating. Since most round balloons, it is recommended not to subject it to thermal shock (air or liquid) hot or cold in order to preserve a good optimal condition. Swollen, the folds are slightly perceptible (superficially) but fade as soon as you play. tried on grass field and dirt (scheduled for multipurpose sports). Inflated to the maximum pressure, reacts normally, I have a bit deflated to clay, to fade a little power bounce. Completely satisfied.
