I have a few nexbelt buckles, but only 1, the odyssey, that doesn't have the flap, I find myself wearing it the most, my others that fold down seem to drop a few times a round, once last round, I really jammed my hand on the corner while it had fallen down, not a huge deal but surprising the magnets don't hold a little better, just walking with my push cart, so no real crazy movements, besides the swing itself!
