It works and doesn't hurt!
I could tell the difference after only one use. My teeth were whiter and brighter. I just wished the box came with more than a 7 day supply. I have sensitive teeth and this product did not hurt at all- during or after. They were so simple to use and not messy at all. They stayed in place for 30 minutes without the product getting all in my mouth,  like most brands do. There wasn't a bad taste or icky feeling..very simple and convenient.  I can't wait to see the results after the 7th use.  Highly recommend!
