Large Helium Tank

Some of my balloons didn’t hold up for more than a few hours.

My tank seemed to be defective all my ballon’s I blew up did not go up in the air?

not as advertised. states would blow up 50 balloons only blew up 24. they look good but only did 1/2 the job

Helium Tank is not refillable , at least that’s what I was told when I tried to refill the tank .

This helium tank, compared to others I've bought locally, does not work as well. The balloons were going down a few hours after I blew them up. It doesn't have the pressure I've had with others in the past!
