They are large enough to cover breasts engorgement that comes along with breastfeeding

Very useful These are way bigger than I expected

I tried the Lansinoh Soothies Gel Pads, 2 Count as well and found them to be really soothing, but their effect didn't last as long as the Avent brand and for the price, I would go with the reusable gel packs every time!I kept mine in the fridge for soreness after nursing or when I had to pump more, I never used them warm so I can't speak to how well they work in that capacity

Ordered these for my wife

They gel is smooth and mallable

The terrycloth covers were a godsend as well
