Hello friends, as I said its a handy bottle so that I can carry it with me anywhere. I am using it from 8 months and never got ill with any bacterial or fungal and upto much extent viral also.
Two things I consider here is its east to use technique and also that it can be used by anyone that is from infants to old people.
A suggestion that I want to add is to decrease its price to some extent so that poor children also become safe from germs.
