Pros: Good price (15$ for 7 top&bottom trays), whitened, good size, conformed to teeth (most of the time), does what it says it will do!, and a few weeks later, while the brighteness faded a little bit, they're still white
Cons: Sometimes would slide around, and can be a little uncomfortable. Can sting gum if not applied properly (it doesn't hurt but it's not comfortable really either)
For the Fourth, I was at the beach (spent a week there) and after being in the ocean, my skin was really nice. I noticed my pores were smaller and clearer on my nose.
Might be adding Sea Salt to my cleansing regimen ;D
Be happy, healthy, and safe!(=
