Review on FlexGuard Support Posture Corrector - Adjustable Upper Back & Shoulder Brace Trainer for Men and Women - Perfect for Slouching, Neck Hump, and Hunched Shoulders - Available in Medium/Large Size by Keith Samuel

This is my first and only back brace, I have no comparison with it but it worked. The downside is that it slides a lot better if someone from behind helps you find just the right fit. And there will be many adjustments. When it's on, you feel it. You are in an upright position with your shoulders back. It's definitely frustrating after a while as you can't move around as freely as you'd like. Ideal for sitting, standing, walking but not recommended for high activity. Once it's off, all you have to do is pay attention to your posture and you're good to go. Again, finding the right fit after fitting and adjusting is important. Not too tight around the neck, slipping off the shoulders, straps are flat etc. Also very very important. Do the stretches he shows you every day!
