Had filled with helium at our local store. A number of the latex balloons had holes in them. Latex balloons also stopped floating in less than 24 hours. The Mylar balloons have held up great though. If you just need them for less than a day, they’ll be fine. Definitely wouldn’t recommend for longer than that.I bought this for my daughters 21st party. I took it to a local party store to blow up the balloons. When I arrived to pick them up they were amazing! Even the party store employees told me how pretty they were.The whole set was well worth it, good quality and lasted through the event.This kit was perfect for what we needed and everything was in great shapeMy only complaint is it is time consuming putting the banner together other than that this bundle is niceITEM: 60th Birthday Decoration Kit. The kit was for a friend's 60th birthday celebration. It had pretty much everything I needed. I'm not usually on the decorating committee, but fortunately one of my other friends has been. Be sure to either rent a helium tank or buy a disposable one, if you want the balloons to float. The mylar balloons use up more helium. Between the latex and mylar balloons, both disposal tanks were used emptied. Per tank, about 20-30 balloons. You should definitely have help, so one or two people can tie the balloons & one to cut the ribbon. Be sure to buy balloon weights. Again, I'm a novice. The regular party planners and/or party givers know these things.I got this in the mail bout a week ago didn’t check it until my party today, cuz why would I open it until the party but maybe I should have done that in the first place, but besides that I was suppose to get a 21 for the ballon but instead got 16The price was pretty cheap as compared to the party stores, so I was pleasantly surprised at how cute this all was. I got this for my sister's 50th party where we went ax throwing. It was a smaller room but perfect for this event. The sash was super cute and she loves purple - which they had. The giant gold "50" was really cute too. If you are looking to decorate for a large party, you might want to order two of three, but for a small get together, this will do the trick.This product was great! Exactly as advertised. My mom was surprised when she got up! Plenty of balloons left over for another time. If you use a helium tank the confetti balloons are loud to blow up! I was doing this at night as a morning surprise and I had to take it outside. Also be aware you do have to string the Happy Birthday sign on your own but that takes about 10 minutes. Great product!Both of the large 4 & 0 balloons both had holes/slices in which resulted in having to patch up with tape the night before (once i found the holes that is), not before wasting most of my helium re-inflating them which meant I did not have enough helium to inflate everything else that came with pack only about 6 smaller balloons... if it was not for the holes and inconvenience, may have been 5 stars - What a shame!!!Item arrived all in order so I just put them on the string and placed on the wall thinking nothing of it but after a while we noticed something wrong we are missing a R ?♀️ Everything else was perfect EDITThe R was stuck behind another letter ?♀️?Was pleased overall with the decorations.Ich konnte alle mit einer Gasflasche befüllen. Das Prinzip ist einfach und die Ballons haben einige Tage gehalten. Die Zahlen haben eine gute Größe und kamen gut an, meine Tochter hat sich sehr gefreut. Kein einziger Ballon war defekt.?Alles super, nur diesen Vorhang fand ich persönlich etwas überflüssig.Kann es weiterempfehlen.Super Ware schnelle Lieferung
