FWIW - in about five years I've had two leaky semi-used bottles, one I
smelled very strongly when opening the plastic bin it was stored in
overnight and the other I heard leaking in my garage after moving some
semi-used bottles around. Sort of scarry, I still use the things but I don't
re-fill them. I also now store them in ventilated areas.
