For flying a really non-threatening kite, in low winds, I find the Prism Atom to be wonderful. For a bit bigger kite flying experience, this Prism Stowaway is just as simple, and fun.
Prism specialises in making kites that are easy to deploy, and fly. I have quite a few kites, and even one or two are more complicated than I care to figure out very often. Prism kites pretty much spring into form, and are ready to fly.
