One of the biggest hangups customers have with home teeth whitening is finding the time for a teeth whitening session. Most kits have power systems attached that are bulky and end up in the closet somewhere. Not the Eclipse LED Teeth Whitening kit! The eclipse has an innovative design that uses the cell phone that everyone carries to power the LEDs. This allows you to carry your LED kit in your glove box or your purse so you can more easily find the time for your whitening session.
