Used the kite in 15mph winds last night with the harness. Felt very secure and easy to control the power. Tested the strop quick-release and it worked fine, but I would like a bigger pull ring..it was a bit fiddley to grab when you're being yanked by the kite. Control in the windier conditions was fine and scudding a few meters was easy. The kite does turn slowly. At the edge of the window it continues to fly predictably and didn't collapse. At the zenith you can relax pretty much an the kite will hover patiently for you up there like a nice little puppy just waiting for you to throw the stick. then weeeeeee! The more I use it the happier that this is a great kite for a first-timer like me.
