Has anyone tried the Upright Go posture corrector?

Body: 

I saw it on Facebook today and am intrigued. It works with a smartphone and vibrates when you slouch - supposedly. You wear it on your back, a small device that sticks to your skin.
I have s problem with going into a slouch when I work at my desk, so was thinking about trying this.
Thanks for any feedback!

Forum:

It looks like an interesting little gadget, though I'm not sure if posting someone's Kickstarter project is an appropriate use of our forum. If you are having trouble "remembering to remember", well, Whole Woman has a video just for that. If you don't already have a posture belt, I would recommend that as an excellent way to help yourself stay on track. - Surviving
