Does the trick however..
Does it whiten teeth, yes!
Although after the first application, it left and continued to accentuate some white spots on my teeth that were not there before whitening and did not whiten evenly. My teeth were only a 3 before whitening and some areas were lightened really well, others not so much. I suppose it just depends on your teeth and where the product displaces while in the mouth guard.
