i'd like to start by saying, i don't usually leave reviews. However this product was excellent. I Wasn't expecting much but was pleasantly surprised. It instantly took brown staines from smoking off and gave teeth a whiter, shinier look. The toothpaste pot isn't re-sealable which is a shame because you wont use the whole pot. but i'm hoping it will still be ok for when i next come to use it, otherwise i'm sure it's cheap to buy. The only other slight down side was that i found getting to teeth which are slightly overlapped by other teeth difficult, but not impossible.
