Runs big
I switch between using a 15 and 17mm flange, I got the 17 thinking it would be perfect, but it runs a bit bigger. Idaho jones customer service is excellent and when I reached out, they let me know their 15mm is still in development and offered to send me a regular 15mm flange insert at no cost. So even though I didn’t get the exact item, I’m happy they are so receptive to their customers.

Great fit
These inserts are the perfect fit for the liquid kits. The provide great suction and the silicone is so so much for comfortable than the hard plastic in traditional flanges. My output is the same as the spectra when I use these with my portable pump. 10/10 highly recommend!

Awful experience
This product absolutely destroyed my nipples. I had never used this brand before but decided to give it a try with my Pumpables Genie Advanced pump, as my usual liquid flanges were taking longer than expected to arrive. I noticed some pain with pumping but didn’t really think too much of it. After a couple days, I started having extreme pain with pumping. A suction level of 1 was bringing me to tears. If it didn’t happen to me, I truly wouldn’t even believe someone if they told me a suction level of 1 caused them such immense pain. Every pull made me flinch until I was literally in tears. I’m 9 months postpartum and haven’t needed a lactation consultant in 8.5 months, but I had her come over to take a look. She said she’s never seen such torn up nipples. Due to pain and in an attempt to heal, I had to pump on such low suction during all of this that it decreased my supply, and then caused a clog, which further decreased my supply. It’s been such chaos over here.. all over this flange. Several hundred dollars in fees and prescription creams later, I’ve finally healed and am back to pumping normally. My supply is slowly returning back to where it was originally. The only thing I changed during all of this was the brand of flange. I’m so mad at myself for not just patiently waiting for my usual product. This was awful. Truly an awful experience.

Works with Legendairy pump!
I got these to try with my Duette pump from Legendairy because they don’t make smaller than 21 silicone cushions. My fingers were crossed that these would fit, and they do!! I’m so excited. They work great, are comfortable and come at a decent price. Will order again.

Fits LM Duette
Had to squeeze the duckbill part on first use so the milk would pass through but other than that these are perfect! No issues with it at all! The tab makes it 10x easier to take off and clean than the brand name inserts

Fits.. sort of.
The flange insert does fit on the Legendairy Duette, but does not perform the same way. While I got suction with my pump, it did not squeeze in the same way the original flange inserts does. It also has a smaller fit so it comes off the edges of the flange easier. It is usable for those of us that are too small for the 21mm, but it is not an exact replacement.

Not Great for Other Pumps
The listing says it is compatible with the Legendairy Milk Duette that’s only partially true. It does not have a consistent seal.

Pumpables compatible
Perfect fit with the pumpables.
