So far so good!
I usually use Crest White Strips, but they're pretty pricey and I'm trying to save money anywhere I can these days! These whitening strips work well. If you've tried the Crest White Strips, then you should have no problem with these. They're super similar in application and use. As for effectiveness, I have not experienced any teeth sensitivity as of yet, and I get that same fresh cleaned feeling with these strips as I did with the Crest ones, so I would like to think that over time, they will hold up and maintain/improve whiteness of my teeth. If you're in the market for Crest like white strips, without the price tag, these are it!
