It worked perfectly to fill up balloons for our birthday party. We got at least 50 balloons from it and maybe more. Would definitely buy again. It's so much cheaper to do it yourself.

Tank says for best results to fill balloons 1-2 hours before party. They aren't kidding! Within 2 hours balloons were on the floor. This is not the same helium as a professional party store.

This helium kit is only 80% helium. Some balloons don't even float. Others barely get off of the ground. Waste of money. Why not charge $10 more, and actually have a product that is 100% helium and usable?

I was very disappointed. We blew up blooms right for my grandson’s birthday party and halfway through the balloons were already deflating. They were also the balloons that came with the tank.!

Bad tank. Blew up balloons but they did not float. It seemed to be air instead of helium. I bought this for my daughter's birthday party. Very disappointing

Didn't fill up nearly as many balloons as advertised and I made the balloons smaller than the recommended size. Was pretty disappointed but maube I just got a bad tank

It blow up far less than the recommended amount of balloons. The tank screw was very tight. Spent $50 but it only inflated about 20 very small balloons. For this amount of money it should be refillable.

I blew up 2 mylar balloons, and they did not float at all. They grazed the floor. Thought I would save money instead of going to a party store. If you want your mylar balloons to float in the air, don't use this.

Did not fill 50 balloons as said & the balloons didn’t even last a half a day before falling to the ground. For the price I paid I was very disappointed

The gas was very diluted, balloons did not last through the party they lasted at most 3-1/2 hours, we filled the balloons as instructed 1 hour prior to the party.
