I've been using one for about a week or so to help me with round ligament pain (like a stitch) on my left hand side, and yes, it does work in easing the pressure and supporting your belly. It is not attractive mind you, but I pop it on under my clothes when walking to and from work and usually no one is the wiser. I find I can't wear it sitting down as it pushes my belly into my chest even more and I find it hard to breath, and it aggravates my heartburn.

I also wear it to bed, which is when the pain is usually most acute, and it definitely helps then too.
