Real-world use and benefits

In daily pumping routines, the right size can influence how snug the seal feels and how comfortable the session is. This BDICOVE set makes it easy to rotate inserts for different days or users, or to pair with a backup kit while traveling. While performance can vary by individual, some users find a better seal and more consistent suction when experimenting with a 21mm size.
