I bought three letters to spell out DAD. The A would not stay inflated. It would hold for an hour or two and then start to deflate. I couldn’t find a leak so I tried taping the valve and it helped a little but not much. Also, the holes where you attached the ribbon are flimsy. I had these outside and it wasn’t too windy of a day. Within a few hours of these being out, the ribbon holes on the two D’s broke and we had to try and tie the ribbon around what was left. Super frustrating and felt like a huge waste of money.Super cute!!!! I got some for my best friend’s bachelorette party and looked very nice with the decorations. The “D” and “E” didn't last filled all night, but it might have been because they were the first ones we filled so we were a little nervous, and we didn’t fill them all the way.Huge. I had to use balloon glue dots to stick on wall because the A " would not float. But still cute. Buy glue dots just in case. Google balloon glue dots. Just incaseWe bought these for our twins, three year old party. Two of them had faulty valves and we had to run to party city to get replacements. Go with another brand.We had the most difficult time trying to inflate these balloons. Once we did they deflated on siteI bought 10 of these 40” foil balloons for a school event. Five of them were defective. Holes, seams welded together making it impossible to inflate. We had to use duct tape to try to cover the holes and make them work but be warned- they are terrible quality. I would like to return them but they ended up in the trash. As you can see in the photo the I, both Ns, E, and last S are all defective.Great! I would buy numbers again for them!Did not have a straw included to blow them up.
