belly bands postpartum?

hey ladies, just wondering what the opinions are about belly bands or those kind of corsets meant for after having a baby?

I was thinking of getting one- my goal is to 1) feel better having my tummy wrapped up since it’s so weird feeling kinda empty now and 2) hopefully get rid of this kangaroo pouch I have or help it at least go faster

I’ve heard good and bad things and was wondering if they’re really safe or a waste of time AND if you do like them what brand or type did you use
