I personally liked the product.
I have to say that this product was very easy to use. Packaging was nice and simple to open. The toothbrush - I liked the appearance of the tooth brush, it looked kind of big at first but the pen fits nicely at the bottom. There is a purple cushion part for your thumb which was very comfortable. As far as the bristles they were soft and I really liked the tongue scraper built in the back. There was a small box of Optic White toothpaste included in the box as well.
Instructions: Brush your teeth as you would normally. It had a really clean feeling and the toothpaste didn't taste weird like some whitening toothpaste. After you're done, you take out the whitening pen and turn it until the whitening gel comes out. Place the gel all over your teeth and let it sit a little. I waited until it looked like it was drying on my teeth and then closed my mouth and went to bed. I made sure not to eat or drink anything.
Results: The box claims to give you whiter teeth in two days. I would have to agree, I noticed my teeth were whiter and I didn't experience that sensitive feeling which was awesome. I would recommend this product. Overall the product was very easy to use, and the box includes coupons as well.
Thanks Influester and Colgate Optic White :)!!
