I only used this vibration plate once, but boy, what an experience. I bought this on a lark, as my own birthday gift. I love the programs, and after just 10 minutes on this, I feel invigorated. Once I got off, I still felt myself jiggling everywhere! OMG. I was laughing the whole time I was on it -- so that alone was worth the price of admission. I am not qualified to conclude as to the health benefits of this machine, but hey, this is better than just sitting around, and since my poor feet can no longer allow me to run or jog, or even walk on some days. I love that there is a low impact machine that can exercise me, on my own behalf.
