I've used one box and saw no difference at all waste of money a lot of money !

Can see a change- have to apply for an hour which is quite lenghty

Packaging is good and I have noticed a difference in how white my teeth are

Would not recommend this product, I stuck to the 14 day treatment everyday and by the end didn't notice a difference so I'm not very happy especially for the hassle of having to wear the strips for an hour and they are not comfortable. Waste of time...

So, first of all i just want to comment on how good these stick to your teeth. When you initially peel them off the sheet, they dont feel sticky at all so i were worried they were not going to stick to my teeth, be super fiddly, and noy stay in place...
