A good product
I found the instructions to be a little vague for a first timer; I had to look up how to use the thermal-form trays.<br /><br />I never got the trays to mold properly so they were uncomfortable for me.<br /><br />Because I was new to this kind of product and I wanted to get used to the trays, I decide to start with 5 minutes a day. The second week I used it for 10 minutes.<br /><br />I have stained teeth from smoking cigarettes and drinking coffee every day, to me they were pretty bad and I used this product twice and I saw a difference.<br /><br /> I will keep using this a few more weeks and see if I can achieve the color I want!
