I saw it being advertised here on this site and thought it was worth checking out, it sounds like a pretty good idea because I have troubles with anxiety in public places and I think the squeezing sensation might be beneficial, a feeling of security if you will. They have testimonials on their website but I'm always concerned of a bias on websites trying to sell you stuff.
