The value is good, but results are not impressive
2 von 2 finden das hilfreich 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.
