Is Gia Wellness water and pendants a scam, or do they really work?

My friend is being pushed to buy into the Gia Wellness program to improve her health. I have been to one of the Gia Wellness get together product shows and when I tried the water and little stones I felt absolutely nothing. I pretended to feel stronger because the girl who took me was dating my son and I didn't want to embarrass her in front of her Gia Wellness business partners by admitting that the water did nothing for me, so I just played along with the program. Even the little lemon test made no difference, it tasted the same before and after. I couldn't wait to get out of there, but then they had to show me the 'income' I could make if I bought the system. It looked like a pyramid or MLM scam to me. I told my friend that if she would just drink more water it would probably give the same benefits as the ih2o water Gia is selling. In my heart I feel this is a total scam, but other people are REALLY putting the pressure on my friend to buy the $2000.00 system "for her health". She doesn't want to get scammed or have to start selling it just to get her money back...Please, I need to know the truth about this company. Lots of people in our tiny community are buying into this and I feel they are being brainwashed and seriously misled by the Gia pushers. I really need to know. Thank You.
