Gimmick? UltraBlu Toothbrush
UV rays are used in water and waste water as a method to kill bacteria. I am not sure if a blue LED can produce a UV ray in that spectrum to kill bacteria. So, yes there is some validity to it, but that does not mean the product is not BS. Also, to much UV can lead to cancer....
Well, now I am going to be flamed out of existance.
