Got one a few weeks back and on first flight it blew a wing tip spar (12 MPH winds). Replaced spar and tried again in 12-14 MPH. Kite is slow to respond, has a lot of over steer and is heavy(main spar) for the low end of the wind rating (3-18 mph). Would suggest that if purchased , first thing to check out is that all lines are connected (mine came w/ 3 bridle lines either not connected or very lightly tied). I have had very experienced quad line friends try this and they feel the same. Kite does offer some unique bridle adjustments ,so I'm not giving this a thumbs down until I can try them all in a reasonable fashion.
Hopes this helps,
