I originally ordered my Imani i2’s with the 32mm breast shields. I later found my left nipple is a tad smaller than my right so I ordered the 28mm shields as well. The 28’s have a beveled edge that more securely holds onto the plastic cups making it harder to accidentally spill all of your milk while doing tasks. The 32 mm shields easily break free from the plastic cups while moving around while pumping. The pour spout cap on the 32mm breast shield is also completely useless. Whereas the 28 mm pour spout cap works great and stays in place as it should. I wish they made the 32mm breast shields the same as the 28’s. Still better than being plugged into the wall with my wall pump I suppose. Love the pumps and the company still! Just giving honest feedback.

I got the 25mm shields as replacements. I wish thhe shields came smaller so I wouldn’t need the inserts too, but it’s a good design, and the material doesn’t pull at my skin. Glad to have these on hand.

I replaced this part after 2.5 months of Pumping 7x per day. I should have replaced them a but earlier though as mine had gotten very loose. I'm surprised that I have had no issues with them leaking when bending over and multitasking while Pumping. Make sure you buy 2 if you want to replace them on a double pump!
