Has anyone ever used the DanceFrame training tool? If so, did it help with your frame?

It's a tubular shaped frame which when placed around your neck and arms locks you into what should be the ideal frame for dancing. It's supposed to work for men and women, and both latin and standard dancing. There are two World Champions promoting it on various dance websites. Just curious. In the video clips, it looks very useful.

Thanks.

I have used the Dance Frame, and found it helpful. Some instructors have also found it helpful for their students.
As you may have seen Showtime Shoes has a video explaining more about the item and its uses.
The frame does come in three different sizes --small, medium, and large. The size that "fits" you is generally only useful for smooth/standard dance frame promotion. A size larger than your normal fit may permit use for a rhythm/latin dance frame -- the video says that it does; I have not tried.

I watched all the videos they have on the device. They claim it helps with Latin as well since the device is aimed at helping you with your frame, but it looks like you would be limited in movement if you tried to dance with it on. But, for smooth/standard dancing, it looks really useful (that's my weak area anyway).

An instructor at my studio warned me that it still won't help with proper posture. In the video, one of the guys mentions demonstrating it at the Ohio Star Ball. I live in Columbus, so I think I'll have to check out the vendor when they roll into town next month. It's kind of pricey at $125, considering it's just a bunch of metal tubes. I realize a lot of research and testing probably went into it, though.
