Re: The Rife Digital Ultimate - opinions please!

I got my Rife Digital professional model from http://www.rifedigitalmachines.com
for the same price as the website you mention. I love the Pro! It's got great new features I couldn't get with the Ultimate, which I used earlier. Like more memory and new modes. I don't know much about it, but I think the silver button contact is essential to deliver the frequencies into the body. I got used to the footstraps and wear them at night for treatments.
