    Working as it says

    Usually I'm sceptic a specially as is not expensive . I used it 3 times I thought that is not working . I did 5th time now and I'm shocked . It is massive difference . Highly recommended, but on my 5 days in a row I could see big improvement

    Worked well

    I am 70 years old, after years of smoking and drinking black tea and coffee my teeth resembled the teeth of a camel, dark yellow. After using the kit they look so much better, OK not film star brilliant white, but certainly much nicer. I would thoroughly recommend this product which is excellent value for money.
