Somewhat discouraged, we give the thing a chance anyway. My husband drove briefly going vot Party and has let the balloons fill a fee with helium. And what can I say. We were pleasantly surprised. Each balloon has shone. Not one was broken. Helium has held up well and the children has made it a great joy when we can rise 10 balloons in the night sky. Was beautiful to watch. 4 inflated balloons were then presented as Encaustic. The daughter of my mind has shone even the next night. The actual burn time was thus even longer than specified in the product description. From us a thumbs up
