Very effective, very impressed
I found it incredibly easy to use and the stains started to lift on the first use. I spend about half an hr on the inside and outside of my bottom teeth where I had significant staining and it lifted almost completely! I am astonished and telling everyone to get one. If I could have one wish it was that there was an even finer head to help get the between teeth stains. This is better than the £100 hygienist visits where they don't even bother to get all the stains off! I have bought products like this in the past and they have not worked well so I am delighted this now exists.
