I've been wearing it for short periods of time for 2 days now. Pros: really good back support (felt like instant relief for my lower back issues); does help me sit straighter; not too uncomfortable for shorter periods of time (30 min - 90 min). Cons: tricky to get on (lots of velcro and ties, like a straightjacket sans sleeves); no bending over, must bend with your legs. Overall: I'd recommend it as a good trainer to help you get your posture in shape.
