Teeth Whitening Light Kit with Photo Initiator gel of 35%

This product really works. My teeth lightened about 2 shades after using it twice. The only con I encountered is it made my teeth extremely sensitive ( which I expected) and also the light tends to lose power quickly.

So I used to use a similar product a while back called white light, hence I am assuming this is the "other version" and since most are the same, I figured the cheap price I paid for was a steal.

I used it once and I got one shade whiter, however DO NOT boil water and stick the trays in for 5 seconds as they shrivel up faster than you can say "huh". I could only use one tray. I dealt with it and it got the job done.

However...the second day my light did not work at all. It was brand new, I bought new batteries from the radio shack and replaced them and it did not work. You are better off buying a higher priced product due to the "lack of built quality" for this item. At least the $50 item can last you several months while this lasted me only one day. Don't waste your money and invest in a better quality light device.
