28cm 25cm corresponds here ..

..if you this balloon inflates. That was my feeling, and it was confirmed to me by a dealer here on Amazon. The balloons have a diameter of 25 - max. 28cm. During normal but definitely bloat under 28cm! Although Amazon / Karaloon indicating otherwise. Thus, the description does not match the product and is not really suitable for high float (too small). What my problems explained by the flight duration of the balloon. I did not come to the specified flight time by far.

The shape of the balloon is very beautiful, roughly equivalent to the product image. And when the balloons are inflated with air or not have to fly long, the balloons are ok. The quality is good. That's why 2 stars.

I can only recommend the balloon caused.
