The balloons were great quality. We used it for an event that lasted 4 days and the balloons held up the whole time without issue. The only problem was that we were struggling to blow the balloons up but I wasn't sure if it was because of the balloons or because we were doing it wrong. So some of them did end up ripped or deflated but we were able to hide those pieces into the balloon arch without anyone noticing. It still looked really nice.
