Review: Game Changer - I bought these flange inserts after realising the standard pump sizes weren’t working for me, and they’ve made a noticeable difference. The included nipple measurer was a surprisingly useful addition — I found out I’d been using the wrong size all along, which explained the discomfort and lower milk output. Pros: • Inserts are soft but durable, and fit snugly into the pump without slipping. • Easy to clean, no milk pooling or tricky corners. • Having the nipple ruler included takes the guesswork out of sizing. • Much more comfortable to use and I’ve noticed better pumping efficiency. Cons: • Only minor downside is I wish more size options were included in one pack, but that’s just preference. Verdict: For the price, this is an excellent little upgrade that makes pumping easier, more comfortable, and more productive. Definitely worth it for anyone pumping regularly
Review: Great value and fits main brand pumps - Amazing to have the measurement kit and several sizes of flanges to work out what fits best. This fits my ardo calypso standard 26mm pump, and 24mm wearable pump perfectly.

### ⭐⭐⭐⭐⭐ Great product
*by J***S on 12 November 2025*

Great product :) very easy to use and found it easy to measure the nipple using the included guide. Used in the Medela pumps and they fit well- can be a bit tight getting them in so adding a little coconut oil helped.
