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.

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?

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.

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.

I purchased this thinking we would be saving money and time blowing up our own balloons the day of my son's 1st birthday party, we were wrong. First off I purchased the Jumbo tank because it stated it would fill more that 50 balloons we were able to fill 10 if that. Within an hour all of my balloons were laying on the floor. My husband had to go to a balloon store and pay over $50 to buy and fill new balloons for my son's party. We were so upset with this purchase and I should have returned for my money back but we threw it away the day of the party! Do not waste your money on this item. Stick to an actual store that fills with %100 helium and will fill as many as you need.

I called around to see how much it would be to rent a helium tank and it made more sense to buy one that you can dispose of when you are finished. Makes for such an easy party setup when you have the helium at your finger tips and you don't have to drive around town with your car filled with balloons and you cant see out your back window. I will be buying these tanks from Wal-Mart from now on.

By purchasing my own helium tank, it’s much cheaper and versatile than paying for a store to fill your balloons. You also don’t have to worry about cramming a bunch of inflated balloons into your vehicle or having them fly away. Additionally, the purchase of some high float makes your helium filled balloons last much longer.

Got the helium tank for my sons grad party decided to try to fill a few ballons a couple days before all the helium was shooting out the top of the tank ..wouldn’t fill ballons - I have gotten tanks from party stores in the past never had this happen.. returned Hoping the replacement doesnt do the same thing!!

I purchased 2 of these for an online pearl party that benefited St.Jude. It was a waste of money. I should have purchased a balloon pump instead, because I would have had the same results. The balloons did not float AT ALL. They remained on the floor. So unless you want to use the helium for a high pitched voice, don't waste your money. I'm extremely disappointed with this product.

I got this on sale and would not pay full price for it. I followed instructions on when to blow balloons up before event and balloons did not last. Some of the balloons fell before the event started. I used the balloons that came with it and some of my own. It’s too bad it didn’t work out for me.
