Query: Not bad, but a tad uncomfortable

This works for what I needed it for, however, I sometimes feel like I need to be a contortionist to put this on. After a few hours of wear, it also feels like your armpits are about to be severed from your body. Over all, it's a good product, I wouldn't recommend long-term use, just a few hours a day at most.
