We thought we would try this since it seems to be the best if the best. My husband & I both gagged just fixing a bottle. The smell is horrendous! I'm sure it deserves 5 star reviews when parents are in need to help a child with true problems/concerns, but it's not worth the money, smell, or smelling results from your baby if you are not in true need for this product due to your baby not reacting well to other formula options.
