ชุดกรวย EasyFit (รวมกรวย 2 อัน + ตัวป้องกันการไหลย้อนกลับ 2 อัน) (4 ขนาด)

The funnel shape fits way better than the last set I tried, and the duckbill valves snap in without any fuss. I've washed them twice already and the silicone diaphragms still look brand new, so no weird warping after hot water.

The duckbill valves on these flanges work exactly as they should—no annoying backflow mess even when I lean forward mid-pump. The silicone diaphragm feels soft against my skin, and having two full sets means I can toss one in the dishwasher while I use the other.

The duckbill valves seal properly without any leakage, which is the main reason I picked this kit. Fitting the flanges took a bit of fiddling to get the right seal, but once in place, they’ve held up well through daily use.
