Review on Crest Whitening Emulsions Leave Ounces Oral Care by Elizabeth Johnson

I was really looking forward to this product, but to be honest it was difficult for me to use it. It took me a long time to really apply an even coat and the little combs at the tip of the pen seemed to rub the gel more than stick it and some parts were very uneven. I also only got about 4 treatments from how little product there was and how empty it seemed so not sure if I applied it too thickly but when I tried to thin it the gel pulled just keep going. for me and rather stuck to the tip of the pen. In the end I just bought the strips and found that I had better luck and got better bang for the buck, the results with this pen don't seem worth the time and price to me personally. Also, I noticed that some people mentioned the stick to apply it and the instructions in mine mentioned it but I didn't have the stick or I had another version of this product so it was a bit confusing,
