We purchased our own 12 inch balloons for an event and planned to rent a helium tank to fill them. However, when we compared prices at O-Go's to rent the tank or have O-Go's fill them, it was less expensive to have O-Go's fill the balloons for us. We were very disappointed to see the 12 inch balloons were not properly filled to their fullest and appeared as if they were 9 inch balloons. I would not recommend O-Go's for filling balloons. It was nearly $100.00 for 60 latex and four number balloons. No small investment for the small size of the balloons. Very disappointed
