With some of the negative comments about meg-mo and plugging for his product, I felt I must respond with my experience. I emailed Meg-Mo regarding their product and that guy responded to me almost instantly. He answered all my questions in a courteous and professional manner. I could not ask for more information or help than I was given. My only regrets after the conversation is that my wife is currently layed off from her job and I don't have the money to get a set of them at this time. But when I do I will be sure and post my results here.
