Has anyone tried a Revitive machine?

Hi there, I get a lot of night cramps and also pain in my right hip, my right calf and my right foot. In the last 3 years I have broken a bone in my ankle and also sprained it, which is why I think I am getting a lot of pain in my foot. I am 72yrs old and I go to Pilates twice a week and Aqua classes 3 times a week and I am beginning to struggle with the aches and pains when doing these classes. However having seen the TV adverts for the Revitive machines with Ruth and Eamonn Holmes I wondered how good they really were. Has anybody got one, or used one and would you recommend getting one? Many thanks ?
