Pretty interesting.
Would love easier inflation, but can live with what we have. Its the fragility of the vynil nipple that bugs me most. When a pump is bending the nozzle over repeatedly they eventually crack. Either that or the deflate valve top eventually rips, or worse, something cracks when its cold.
I just figure its time to evolve away from the pool toy parts.
I can see the hesitation to move to a proprietary pump nozzle. But not enough to stop progress. If your worried about it go one step farther than the other guys and include a few cheap hose nozzles with each kite. That way people can throw one in their kite bag so they can use it with a budy’s pump in a pinch.
