DiscreetDuo 穿戴式吸乳器-隔膜（單入）

The diaphragm fit my wearable pump perfectly and suction felt like new again. I only wish it came in a two-pack since I'm ordering a second as a backup.

Was about to buy a whole new pump setup when I realized I only needed this one little diaphragm piece. Popped it in and the suction came right back to where it was when everything was new. Genuinely relieved I didn't have to replace the entire thing.

My pump had been losing suction for weeks and I couldn't figure out why until I swapped in this diaphragm. It's a single piece that pops right into the pump housing and the seal feels tight again. Back to full suction on the first session.
