I buy this after see it on tv . honestly , I be skeptical , just like all the other buyer of this product who give it good review . after receive this and try it out , I would say it work . it will not be a miracle product for everyone , you still have to put some effort into use it . although it do make you look silly , you can always do it in the privacy of you home . my only qualm about it be that it can be initially hard to use at first and can slightly painful for people with soft hand . nonetheless , I give it 5 star !
