Bests & Worsts Reviews from Amazon

So I got this bed sheet after reading some interesting health reviews about the benefits of earthing. I started to use it and yeah, noticed some health benefits like better sleep and improved recovery from workouts. I followed all of the advice that comes with the sheet like don't go to bed with lotions and oils on and don't use bleach, but guess what? At about the 9 month mark my sheet started to lose it's conductivity. It wasn't completely gone, but large patches of it had lost conductivity. I went on Earthing.com and chatted online with a customer service rep about the loss of conductivity at the 9 month mark and she told me "well those sheets only last 1-2 years, that's just normal wear and tear on the silver" Nowhere on the website or on the package the product comes in does it say "expected to last 1-2 years". That's downright dishonest! Earthing.com knows most people wouldn't spend $200 on a product that has a one year life expectancy so they just leave that part out, how convenient for them!
