Review title: Not Satisfied
Product review: I used this product for a week straight. I used it at the same time every night, and brushed my teeth prior to use just to make sure it was actually whitening my teeth and not food residue. I also took pictures prior to each use to see the progress. My upper teeth whitened slightly (mind you, my teeth were not even very yellow or discolored to begin with), but it did not whiten my bottom teeth at all, at least not noticeably enough. Also, the gel always stayed in the upper tray, but always leaked out of the bottom tray which is why I think it didn't work. I was not satisfied and feel like I just wasted $35 and people will not even notice a difference.
