Review on 🎈 Premium Quality Latex Balloons - Assorted Colors, 12 Inches, 110 Count - Ideal for Birthday Party Decorations by Andrea Allen

Filled these balloons with helium on the eve of my birthday. In the morning they all lay half empty on the ground. Very disappointed. If you plan on using helium to inflate, look elsewhere. After submitting my review I was informed that a full refund had been issued. Also, a few days later, I received a package containing 100 Winky Boom balloons (doubling my original order). I really appreciate this kind of support from the seller. However, the packing list for the balloons stated that they were made from helium-grade latex, but this was not stated anywhere on the balloons' packaging. I'll have to test this and give an updated review later. Update 6/19/19 I received a second pack of these replacement balloons. Thanks again to Winky Boom support. But no refill pack works better with helium than the first. I checked the balloon's helium fill this afternoon and it was on the ground in just 3 hours or so. These are great balloons if you don't plan on using helium with them.
