We have had these kites for about two years now. We bought them in the beginning of spring with every intention of using them....then they got put away and forgotten. Until now.
It was really windy, so it was quite difficult to keep them up once they became airborne. In fact, they became a little bit scary and I thought someone might just lose an eye. But they didn't.
However, I would not advise flying kites in 30mph winds......just a tip!
