Not really recommended
I found the instructions lacking. They said to adjust the straps first and then put them through the buckle or loop. I think that is reversed.  Then it said not to pull too tightly because it can worsen circulation. So that is a bit scary. How do you know you are worsening (not cutting off) your circulation yet pulling it tight enough that it is helping with posture? I certainly don't know.. I found on the first day there was some relief to my shoulders. The second day, the pain seemed to transfer to my neck which was unbearable. So this one is not for me.
