I think it works okay. My teeth aren't sparkling white, but some of the stains are gone.

I have used another Crest strip type before and was really pleased, that made a big difference with just one treatment. This one's instructions said to use one set for three days, using no more than two kits a year. I did the three, and my teeth still aren't the bright white I got like before. I don't smoke, and drink about 2 cups of coffee a day.

The delivery was fast and everything was okay with the product. However, I expected results that would last me longer than just a few hours. I've heard from other people that they got long-lasting results, so maybe there's just something about my teeth that the whitening effect doesn't last that long. I would recommend it for users who want instantly whiter teeth for a special occasion.

I’ve used this particular brand and type for a few years. It works great! Really does whiten!

I highly recommend Crest Whitening Strips. I have used more expensive products in the past and got good results. I believe that Crest Whitening Strips gives same result or better at a lower price point.
