I would like to see it in use for a few years, before I made an informed decision.
My concern is that, yes, it may help reduce the pressure in one area of the body, but then that pressure has to be compensated for somewhere else in the body. It straps around the neck area, attaches at the elbows, the waste and levers at the shoulders; after a year of use, will those areas of the body now suffer because of the extra strain... and what problems would that cause?
It's a shame, but the images don't really inspire confidence in the product; (it just looks cheap and tacky) and the video is all but useless in giving any information.
I genuinely admire people who can come up with these ideas to help make people's lives easier, but I think the execution of this product and it's marketing does not inspire any confidence in me.
