The last picture, on the left is a before, and on the right is an after.
If you look at it closely, you can definitely see the difference where my teeth is lighter by 1 shade.
Application wise is easy, where you just tear off the strips and stick it onto your teeth symmetrically.
Although you might feel a tingling sensation on your gum (yup, that's the chemical working hard on scrubing your teeth), but if you still feel unpleasant after removing the strips, just brush your teeth after that.
But I would use the strips after I brush my teeth and apply it for half an hour and voila, its done.
I would give a 4 1/2 star out of 5 star as I feel that the grasping power (or should I say that the design) for the lower strips isn't that good enough. Had to reapply it quite a few times.
All in all, a good product that I would recommend to all.
