I used the strips for 14 consecutive days. I tried to have them on for the full hour each day, and most days I was able to do so. Applying the strips was easy most days. There were a handful of times when the lower strip would slide off while applying.
The end result was disappointing. I now have some white spots on a few teeth. Had all the teeth whitened to the same white as those spots, I would have been satisfied.
The pain I experienced was minimal. I do have extremely sensitive teeth and gums. I appreciated that the pain was minimal.
