This product really works for aches and pains. I use it at bedtime on whatever happens to be aching that day - sometimes it's my knee, sometimes my wrist, neck, whatever. And it definitely takes the pain away. And no smell!!

I listen to the dvds on my way to work and back, and I can learn at my own speed and repeat each session as many times as I need.

Good software, but a terrible activation system. I had to register the product and set up an account before I could activate it, since the initial activation page does not allow you to enter the entire product serial number and it said that my serial number was invalid until I completed the registration and was able to enter the entire product serial number.
