This pen is so easy to use. Just click it and 'draw' on your teeth before bedtime. In the morning just brush your teeth as normal. Within a week you will notice whiter teeth. I had one stubborn stain between two lower teeth in front that I can never remove. After just a couple days of using this pen the stain was gone! My teeth are very nice and bright white now. The pen can be used for several applications as you only need to use it for one week at a time. Much easier and more comfortable to use than the whitening strips.

I am not happy with the consistency of the product The pen tip gets hard and chalky after the first use When reading the booklet there are a lot of do and don’t s to follow and after following all the directions the tip still is hard and chalky I do see a slight improvement in my color I bought this because it was a very good price I have use other whitening pens and they glide on smooth and clear and the tip stays clean after whipping it with a tissue Overall I will probably not purchase this item again

Easy to use. It worth a try. You can’t go wrong with Colgate products. I decide to try the Colgate Optic overnight teeth whitening pens because I trust the Colgate brand.

This stuff is supposed to be great….I found it hard to use, and no more effective, and much less convenient, than less expensive alternatives. The application brush broke after two uses…

great price, but as far as using it, not pleased using it. Didn't realize that this only does the front teeth, Also, no drinking anything during the application time (night time) I am a tray user and more comfortable with them
