[Q]: This product had great reviews before I bought it, but it didn't seem to live up to the hype. There was no difference in using this with or without it. It took 2 months for me and my mom who has arthritis pain while trying to get rid of some bad knee pains after knee replacement surgery and she never noticed any difference. Not sure if I'm wasting $20 a month on an ineffective product. Maybe will try one other product, maybe not. Don't waste your money.

Bad review
