This book describes a simple inexpensive way to improve dental and overall health. Modern medicine suggests root canals and /or pulling teeth with a dental implant to follow. No thanks.

Works very well.. Less time spent blow-drying my hair. It works well but tends to want to come loose.

On day three after installing the light, one of the lights small LED lights is not working . Now a month later both sides have 2 bulbs out. It makes the lights look horrible. Overall this product seems flimsy and cheap. Not a good purchase..
