Not terrible !! i’m a thinner guy and i can wear it on my chest like i prefer to or my waist. but i also only use this to keep my posture while i figure skate and a reminder, so i can’t speak on how well it works for normal use.

Great! I think wearing the strap over the shoulder can help prevent round shoulders, but it might get sweaty in the summer.

It's great, I notice how the back is straight and it's very comfortable. I recommend it; the device is fantastic, better than I imagined. It's really good, although the sizes are small. I had to get an XL and even then the waist is small; it fits just right, but still, thank you.

It's perfect, but be careful, it runs small with the L size; you need to be slim.

I just received it and I'm already wearing it. Very useful.
