I got these thinking they would be cool, all it is a plastic bag that the air don't stay in and a lighting cable thay goes in it but dont stay in and you can't even keep the air in itThey are so pretty but I don’t know how to assemble them and they didn’t come with anything on how to assemble them so I am stuckAfter a day the balloons start to deflate.Zero stars.. This is awful. Description says balloons inflate to 20 inches, that's a lie. They are these tiny plastic, not latex, balloons that do not inflate at all. I have a helium tank and it fills the balloon up but doesn't expand it and bc they are plastic, won't float. Balloons are absolutely useless garbage. Don't waste your money. Just buy led lights and attach to regular balloons.This is truly a waste of Money not at all of what it description. I really wish I had read the reviews this mess is the size of your hand and it don’t expand. The plastic is like a beach ball not latex don’t buy if you’re looking at the description. What a wasteNothing about this product was good. The balls/balloons would not float with helium. Terrible product. Please don’t be scammed and order this productThey were for a retirement party and graduation can I couldn't use them at all Im so sad ?Everything was bad nothing like the picturesArrived as promised by Amazon.Easy to assemble. Lasted over 3 weeks ( I had to deflate myself). I attached tape on the lights to proved extra stability . Would have been even great if it came with balloon sticks.Balloons don't inflate lights are difficult to feed into balloon looks like a lite up pancake very dissatisfied with this purchaseThe balloons turned up and we ordered multi coloured ones and they were xmas colours we blew them up to the 20cm like the instructions said and they did not.float they burst when we put the helium in themBaloons don't float with helium. UselessIt's very small and doesn't look like in pictures at all.
