I used the kite line mounts for the insta 360 x 3 and looks like it will be used for the X4 as well for one session kite surfing in light wind and the mount with very sharp edges cut through my safety lines which is very dangerous as it could have dropped me out of the sky during a jump this has been machine cuts and left sharp edges which seemingly are incompatible with kite Lines and needs to be redesigned unless for some reason this is a mistake on only my model and other model pipeline mounts are smooth down and not damaging kite lines.
