Thanks for the headsup, i run with the smaller Lifesaver bottle and haven't been ill from it ever but they recommend discontinuing use until they complete the new series of tests, if it turns out to be recommended not to be used i want my money back and i'll consider myself very lucky i was not made ill every time i used it.
I just bought a Lifestraw Mission 5ltr last week as a lighter system filtering option so I am okay for any possible upcoming adventures
