I find this story a little scary - we are playing with our lives when kiting and accept that there is always going to be some risk, however I find it appalling that a manufacturer would sell equipment that wasn't up to the task. I bought a Maui Aviator harness (it was also the cheapest in my local kite store) but it at least has a solid metal spreader bar with a substantial looking hook. At the very least I would expect the harness to have a safe working load equivalent to the combined breaking strength of my kite lines - in excess of 1,000kg on my Venom. I'm glad that your friend suffered no serious injuries, hope you have more success with the Maui harness.
