I found this great for helping to work out lumps that particular hard to get to.
Note that you really need to be careful with the amount of pressure you apply with it. I was using the firmer edge to work out a blockage and ended up with terrible bruising. Adding some olive oil to my skin has helped me use it more softly when working out lumps.
I came home from hospital with sore lumpy breasts and now I use this massage roller before feeds and its amazing, gets all the lumps out and helps with my milk supply
super easy and comfortable to use as well as effective! Love it. Thank you
