Bests & Worsts Reviews from Amazon

This arrived quickly as expected due to Amazon Prime, and was packaged very neatly in a translucent and reusable zip closure bag. It was a little bit awkward to get into at first, but once I realized i would need the (included at no charge) extenders I was able to slip the corrector on and finesse my way into a proper fitting. It was a trifle tricky getting the correct settings at first, as I tended to overcorrect or undercorrect the velcro positioning leaving the centerpiece in the back off-center, but once I had it optimized I found I only needed to undo a single strap to take it off. Pros: Works as advertised. I sit a lot at a computer, and I found it was gently forcing me to sit more upright Seems durable and well made Considerable adjustability with the long Velcro closures and included extenders Not noticable under a dress shirt or sweatshirt Cons: The straps under the armpits were irritating for the first few hours Took a bit of trial-and-error tweaking to optimize fit Visible under a t-shirt Overall, I am very happy with my purchase and look forward to utilizing this posture corrector to hopefully undo some of the strain I've placed on my back and shoulders from my deskchair-centric life. UPDATE: After seeing my review, an agent for the seller contacted me and asked me if I had any questions about the product and if I'd like assistance in getting a better fit to make it more comfortable. After about 20 minutes of finagling, re-pulling straps, and other suggestions I was able to alter the straps to such a means that was much more comfortable yet still seemingly effective. They didn't need to the time to help me use this product correctly, a pdf or website would have sufficed, but that an actual CSA walked me though the process was impressive. For their caring demeanor I upgrade my review from 4(.5) to 5 stars! Kudos!!
