Love it! I have been using it everyday for 2 weeks and my teeth are all the same colour now. I had darker coloring in the region close to my gums. Have bought another one to give to my nephew.
With this I managed to remove these small black marks(from all the black tea i drink) that have been on my teeth for years! It required time and patience but we got there in the end. Very happy
Love the packaging and design. I thought it may be painful but its definitely not sore to use at all.
Works great. The only thing you need to consider is how to use it effectively. It is time consuming but works.
