Hi @rola,
Before I saw Margaret Martin's podcast on Whole Body Vibration, I purchased a high intensity vibration plate exerciser. I used it for about nine months. I wound up giving it away after hearing Margaret Martin's warnings about its dangers. Dr. Lucas mentions that's the type for building muscle.
There are other discussions of Marodyne on Connect. You may be able to find the posts by searching Marodyne. Good luck!
