Real-life scenarios and tips

Use the ruler to confirm size before pumping. Keep the storage bag handy for on-the-go setups. Consistent cleaning helps maintain performance and hygiene, while testing sizes during different sessions can reveal what feels most comfortable over time.

• Try a 15mm or 17mm for close-fitting comfort during shorter pumping sessions
• Move to 19mm or 21mm if you notice gentler suction and a looser feel
