Review (5/5): Work really well, hard to put on.
I had NASTY yellow teeth through highschool, which only worsened when I drank coffee. Don't get me wrong- I tried using toothpastes every morning and night that promised whitening effects, but they honestly didn't work. So I tried Crest WhiteStrips.
Pros:
They worked SO well. EVERYONE commented on how good my smile was.
I didn't even use the whole pack at once. I was so inconsistent with it, but it worked so well anyway.
Long lasting effects. I've not used them for 2 years, and now I'm considering getting another pack.
Reasonably priced.
Whitened my teeth without making it obnoxiously white
Cons:
They made my teeth sensitive
Hard to put on
I didn't know what to do with the goo that was left over...so i spate it out. (tmi? sorry)
But overall, I'd recommend this product :)
