Query: Not a great fit to keep suction for all breast sizes

Worked great when I was engorged, once I was not filling up as much I had a hard time getting this to keep suction, did not work well staying on when I tried to use on my other side when breastfeeding, its a great concept but only ok in actual use, I never used it on its own, only when feeding
