I sat for 30minutes with the gel strips over my top and bottom row of teeth and was amazed at the result when I peeled away the strips. I for one, thought it wouldn't work instantly and that you would need to keep doing it for so many days to see any result whatsoever! 

(Luckily they sent me a batch, so I have a few to use again *grins*)

I can't wait to see how white my teeth get! 'Do you use the same dentist as Simon Cowell?' I did I hear you say? ;)
