How long are the helium balloons that you have supposed to last? I got several on Saturday evening and at 10am Sunday they were sitting on the floor. I was very disappointed. They were for a baby shower that we had on Sunday afternoon.

The shiny ones last longer but it's funny I got one from the dollar store it's about a month old and it's still floating the ones I got from PC barely lasted a week... But in my case I don't think the young lady inflated them correctly. Cause she was really nonchalant about even helping me that evening..

Latex balloons last 6 to 8 hrs. There is hi float they can put in them to make them last longer.
