Love the Idea, maybe not right for NYC.
I was told by my acupuncturist that I needed grounding, after watching the documentary I was excited to give the earthing pad a try!
We had only one grounded outlet in our apartment, I have felt little difference using mine, but my partner has found it to make him very jumpy and feel like there is too much of an electrical charge in his body. After further research we found that perhaps being on 5th floor apartment in NYC is not the bets location to use the earthing pad as we could be getting electrical currents from all sorts of things appliances, the fridge, neighbors etc.
We spoke to an Ayurvedic practitioner and they didn't advice it for us in our current home.
I think the pads are a great device and wish it was working for us but think perhaps not suited to apartments in busy cities like NYC.
