I need opinions please.... are they worth the investment? which one is best? experieces? pros and cons? 

TIA.

I have no experience with either machine. I've always been skeptical about all the therapies offered to the horse industry. But I will say there is definitely something to this type of therapy. Recently my husband was hospitalized due to asthma. Each day he was placed on a human sized version of this, it most definitely helped his breathing by breaking up fluid in his lungs. We hope to purchase a theraplate for both our use and our horses.

thank you so much for your input!
