Equate Dental Strips don't work...?

[MMAFan26]

Ok, first off, if anyone has ever wondered about the Wal-Mart brand of Crest White strips, like I did, I can say that I don't think they work. I just finished the 14 days of using them, and I can't tell any difference in my teeth, and if there is a difference, then it is very very minimal.

Anyway, I haven't actually tried the Crest White strips... I was trying to save a few extra bucks going with the Equate version. But, do the Crest White Strip Premiums significantly whiten teeth? I'd like to know before I blow $30. By the way, incase anyone is wondering, the Equate strips I used are supposed to be comparable to Crest White Strip Classics. But if I am going to buy the Crest version, I'd buy the Premiums which is why I am asking about those.
What about the Listerine strips?
