Thank you for your responses. I'm glad to know that I'm not alone in my thinking.
The comment Jennifer1981 said is exactly one thing I had wondered about. I already have an irregular heart beat at times & wondered if, by chance, shaking my heart around would hurt/help or really not make any difference whatsoever.
My husband's insurance is changing the first of the year & EBI? (anyone heard of them), will be a preferred provider and from what our insurance rep said, they sell vests. I plan to call & see if they offer all of the vest options.
I just want to be well informed before I buy something that has that many zeros in the price! It's hard to believe that you could buy a nice car for the same price!! But then the car wouldn't be covered by your medical insurance-LOL I wonder which one would last the longest though (the car or the vest)<img src="i/expressions/face-icon-small-wink.gif" border="0">
