So far so good. I am wearing this for short periods and it seems to be helping my posture. I possibly should have got a size S as I have a small upper frame but it has also been nice to ease into it with a bigger size.
Great to use, must use shirt underneath it other wise it's to uncomfortable though.
I use this when I ride my horses and it had improved myself and my horse so much. Love it
I always had low level dull back ache (rhomboid region) throughout my life but it is exacerbated by long working hours on the laptop and stress. The posture corrector alleviated my constant nagging back pain within a week. Note: I only used it during working hours.
