I have not had any problem to inflate the balloon with my bicycle pump and an inflation needle specially provided for this purpose. I havent even put lubricant. Keeping it slow, it works. There still has a place at the dune sewing level, where I see a slight prominence which does not affect the quality of play, when playing on grass. The ball is in shiny plastic coating that quickly sabîmera on concrete or any hard surface but grass is no problem. It is hard enough and especially less heavy than most balloons workout quon located. To see lusage but for now, not much to complain about.
