I've been trying it for several days using it in my shirt's left pocket. Focusing is a problem, because you don't see what the lens is capturing. The sound many times is not continuous.

I have been taking these for about a year. 3 months after I started taking them my hair was thicker and healthier. I was losing my hair from low iron levels and anxiety, this pill has given me one less worry. I will continue to take them, and would recommend anyone losing hair to give them a try, they worked for me!
