Dont recommend
I bought this product thinking i would have greater suction and shorter pump times however found the opposite to be true. The suction is very poor when this shield is attached or the item delivered was faulty/low quality. I personally found that the shields without the silicone work much better.

High-quality, comfortable, easy to clean and use!
The Medela PersonalFit Flex Breast Shields (2-Pack, Small 21 mm Flanges) have made a noticeable difference in my pumping routine and are a standout accessory for anyone using a Medela breast pump. These breast shields are thoughtfully designed with Medela’s PersonalFit Flex technology, which really enhances comfort and function compared to traditional rigid flanges. One of the things I appreciate most is the soft, flexible rim—it adapts gently to the breast’s natural shape and movement, helping to reduce the pinching or soreness I’ve experienced with other shields. The 21 mm size in this pack fits me well and helps create a good seal, which I’ve found contributes to more comfortable and effective pumping sessions. For anyone who might hesitate to pump because of discomfort, these feel like a real improvement. The shields are very easy to attach and work seamlessly with most Medela pump models, so setup is quick and hassle-free. Having a 2-pack is especially convenient: I can keep one on my pump and have a spare ready to go, which is great for busy days or when I need to switch between locations. In terms of performance, the PersonalFit Flex shields optimize milk flow without causing irritation, and I often finish pumping feeling much more comfortable than I used to. This personal experience makes me confident in recommending them—not just for comfort, but because they genuinely support a more effective pumping experience. Overall, the Medela PersonalFit Flex Breast Shields in Small 21 mm are a high-quality, reliable accessory that I would recommend to other parents seeking better comfort and a custom-fit solution for their Medela breast pump.

would recommend
These are even more comfortable than the originals that come with the pump! I had trouble getting the perfect size; I had to order a few different ones until I found the proper fit for me but I would recommend these. For the amount you're pumping, it's worth the money for the comfort!
