Doesn't work for me

This product does not work well for me because it doesn't whiten up my teeth at all. It leaves it the same color and my teeth arnt the whitest. I bought this so it can whiten up my teeth but I'm very disappointed

I was quite disappointed with this Crest product. have been using Crest for years so when i saw this one i was looking forward to trying it. The taste is not great to start and as son as you put the gel in your mouth (the 2nd step) your mouth/teeth feel so cold it almost hurts. i continued to use it though 2x a day for 2 weeks to give it a fair try and can say it is not worth the money in my opinion sadly. I noticed no difference at all.
