I love this product because it is a concentrated form of silver oxide. One bottle is enough for my whole family. I have been using silver products since 2011 and I am impressed by the quality of this item. I ordered 3 for my family and one for my mother who lives in NY state. I am recommending this product to all my love ones during this critical time of the Coronavirus Pandemic outbreak.
