It's a catch 22, I think.  In order for it to work well, it has to be tight.  Because it's so tight, it can get uncomfortable.  I got it as a compression garment after having abdominal separation after giving birth.  The lump in my abdomen was not visible at all and my clothes looked good on me.  It gives great support to my back and works day after day.  That said, it will get uncomfortable after several hours.  I still would recommend it over other products that are less tight but stretch out easily and stop working as well.
