Title: No "green dot" as per instructions
Review: THe instructions say that the shelf life is very long, which is why I chose this product. I am not sure if I got a defective bottle, but I filled it with water as instructed and waited for the indicator dot to appear to let me know the dilusion level for adding it to water. The indicator strip on the bottle never changed. I waited a week before sending it back. I may have gotten a defective bottle, but am now looking into the iodine tablets instead.
