Seems to work good,but....
i wanted to write about this, because i  read reviews and  maybe a lot of others do,too. This probably applies to all the products made like htis, with the straps you have to pull around and  attach (velcro) on the shoulder straps in the front.  i  felt this would help me, I tend to slouch and my back is tired and  aches.  I received it yesterday, and took me awhile to figure it out, the directions are simple, but  for some reason i thought the adjustment straps went around the waist.  looking at the pictures I figured out they go up the  shoulder straps in front.  Then, i got it on but couldn't reach the straps in the back to pull it tighter.  if i were thinner (my chest isn't over 50'  it says it fits  50'hest)  and did more yoga, i could probably reach the ends of the straps in back.  There is no one else here to  do it for me.  i gave up last night and this morning took2 long strips of  material and sewed them tightly to each end of the adjustment straps, (wrapped the thread  around the material and strap tightly to hold it ) so i could pull it around and tie it in the front, instead.  This worked fine, and as soon as I did it, the pain in my back started to fade.  I am giving this 5 stars because it does work, and it looks like the more expensive ones, that work the same way, and it's me, I am not  thin and flexible enough to grab the adjustment straps in back and pull them up on the shoulder straps  like it's supposed to be used.  Even if i got one that  came around  in the front, instead of on the shoulders, it still might not be easy to grab the  straps in the back to pull them around. unless they were very long, like how i  fixed this one.  They seem like they are made for  thin, flexible people, or for someone with  help. (you can't put the adjustment straps on before putting it on,  it has to open up to get the arms in).  other than this, it has possibilities.  i'm  attempting to lose weight, and maybe when i do,  i will be ble to use it the way it's meant to.  Though i'm also hoping it will help m back and i won't need it at some point.  it does make my back feel better.<br />[ I am editing this because after awhile how i had the pieces of material to tie around my waist attached to the  straps,  didn't stay on good. I then made  a slip knot in the long strip of fabric, and  put the strap of the brace in this, pulling it tight so it closed up on it and wouldn't slip off. On both sides. Now I can  get hold of the straps in back of me (the material I attached) and pull them around in front  and tie at my waist.  As I said, I think a thinner  more agile person wouldn't need to do this and could use it the way it  is.  as i lose weight do yoga,I hope I will be at that point sometime. But it does make my back feel much better and is soft and comfortable to wear]
