Keeps the helium surprisingly long, now already 12 days and still not collapsed!

Manufacturer's Anagram.
Unlike purchased from me about 1.5 years ago and very badly failed Anagram Balloons (Only with XL referred, some holes after delivery, helium lasted only 2-5 days, depending on the specimen) is obviously improved this model ( "Anagram helium Saver XL") at a *** multiples *** *** *** ausgreifter.

A second, red heart-shaped balloon (also Anagram helium Saver XL) also floats for 12 days yet, but it's clearly escaped helium.

It may be a coincidence or Disney requires particularly good quality control.

Very surprised I am, however, of the same manufacturer on the huge variation of quality. After all, it seems to massively developed positively.

Very annoying is the fact that you get from Amazon under a single SKU often every few months only partly similar, but only rarely permanent the same product. Therefore, this review be completely wrong in a few months, if manufacturers and quality have changed.

Amazon suffers apparently under ASIN shortage, otherwise I can not explain why similar products offered by often completely different quality or with slightly different facilities under the same ASIN me. This concerns not only helium balloons, but also eg a USB3.0 PCIe Card --- there can be some reviews not explain and sometimes holds the creator selbiger for goofy. In truth, however, the product was "secretly" replaced by a worse.

There are now better USB3 card even again, however, the same reviews (unfortunately that is also far too often for only similar but not precisely identical products before) --- the reviewers and potential customers are likely to feel ridiculed:
B00EA0C9ZK vs B00F9XGPTI
While this is both USB3 card but 2 totally different products, but behind the same hang reviews.
With balloons still more acceptable but also annoying.
