I have never been so happy with a purchase. It was definitely worth the money.
It worked the very first time I used. The direction says to use two cups each time, one for mouth and one for throat. I guess you can use only one cup to wash both mouth and throat. This way it will last twice as long.
Also, it is recommended to use it twice daily, but I have been using it once a day in the morning, because unless I am waking up next to a girl, I don't care if my mouth smells during night time.

Summer's Eve is a great product. Some doctors recommend it and you can never have enough. I like that these are the larger bottles, in the store you mostly find the smaller ones. Will be buying again, but I won't need to for a while now.
