I tried the Crest Whitestrips Premium, and was pretty impressed with the product. I didn't find the strips to be as difficult to put on and deal with as some people have said. You should be prepared to not talk too much for the 30 minute times that you have the strips applied. Read a book, watch a movie, or watch some tv for a few minutes, and the time flies by. I found myself pressing the strips down several times, just to make sure that they were staying in place, but that probably wasn't necessary. The results from this product were impressive. As advertised, I did indeed see noticeable results in the first couple of days. I didn't expect much coming in with the low price tag (relative to professional whitening). I would recommend that you give this product a shot if you can be patient for the 30 minutes twice a day, and not talk or move your mouth around too much.
