How?

Crap! I was googling about premier pure, I found this video on daily motion

http://www.dailymotion.com/video/x13jjkw_premiermag-premier-pure-premierpure-magnetic-therapy_lifestyle 

I need help. How do I know the sources of this video is real?

Can believe or not to believe?

And what if the video is true, what should I do for my parents magnetic bed? 

Will it still be effective ?

Then this virtual pole tester for app store? Anyone tried it? Is it real or a gimmick?

Anyone bought this app before? Cause if it's really south, what should I do? 

I need some Sane advice, can anybody help?
