LaVie Lactation Massager
This device spares my severely damaged wrists from have to compress so much or so hard. I did not find it magical for recurrent clogged ducts, which was what I bought it for in the first place. If ducts are very clogged, ultrasound therapy is the only thing that works. If ducts are mildly clogged, or if you're like me, and you want to do lots of manual manipulation to empty the breasts more completely to improve supply, then these really helps lighten the strain.
