I've been using this mouthwash for just over 3 weeks now. It's lovely to use, refreshing but not too harsh. I don't think I have noticed any obvious whitening however, although has maintained my teeth well. I bought it on offer but unsure if I would be prepared to pay full price unless I suddenly get noticeable results.
