One use and my teeth are noticeably whiter. Tried the charcoal stuff that makes your gums black and was NOT impressed. Have also tried trays with the bleach gel (my wife paid a lot for special moulds) but these seem to deliver whiter teeth right away. Not used the full 'course' of a pack, but may do one day when I have to meet the queen or something.
