I feel like there was a post about this years ago but can't find it. I'm thinking about getting a posture corrector for DS (age 13) and wanted to get feedback from those of you who have any experience with one. I was considering buying something like this: https://www.amazon.com/Andego-Back-P...rector+for+men

If you or your child have used one, did you think it helped? How long did you wear it per day? Which model did you buy? For reference, DS is 5'11 and 120ish pounds--very lean for his height. He is interested in wearing one to help his posture, but wants to make sure it's not obvious and also that it is comfortable. Thanks in advance for any feedback!

ETA: The main issue we are looking to work on is slouching.
