Review on Get Brighter Smiles with EZGO 10 Pack Teeth Whitening Gel Refills - 22% Bleaching Gel, No Sensitivity, Ideal for Sensitive Tooth Whitening, Compatible with LED Light and Tray - 10X 3ML by Amy Fuhrman

I am surprised that this product has so many reviews. I've been using it for 3 weeks with no improvement (as evidenced by the tooth color indicator that comes with this product). I mean, I think my first clue should have been that they shipped 10 tubes of the product. That is much. Price $2 per tube. I'm not sure what to expect from a $2 teeth whitener. I tried the first week without the light because I didn't even realize I needed it. No results. Tried the next 2 weeks with light for 15-25 minutes per treatment. Still no results. Lost only $20 and a lot of time and hassle. I will throw away the other 8 tubes as there is no refund or guarantee on this product (something else that should have given me poor product results).
