Agreed. I ask my students to wear it and it certainly is an eye opener for them; having a good frame makes the dancing work! However, without training, they almost immediately revert to their old posture. In the long run the student has to be able to create the frame from within their own body.
We know other couples that had previously bought a Canadian frame (similar look) and others who have tried broomsticks etc, but this is the first product that actually works...and is a pleasure to use!!
