Balloon Time Disposable Helium Tank 14.9 cu.ft - 12 Silver Balloon Weights + Curling Ribbon & Flower Clips for Birthday Parties, Baby Showers & Wedding Decorations

I was worried, after reading some of the reviews, about this helium tank. However, it was so easy to use, and the balloons stayed up for hours!! We blew them up about two hours before the party (around 5 pm), and they were still going strong when we went to bed that night (around 1 am!) - everyone knows that latex balloons don't hold the helium very long, but this tank did just as well as store bought balloons! And, I still have some helium left in the tank. If you need to blow up around 40 latex balloons and have them last all day, this is a great tank for you!
