### ⭐⭐⭐⭐⭐ Really good inserts
*by K***R on March 22, 2023*

I ordered the 21mm 3 pack. They work really well. They fit very snug in my spectra flanges which makes sure my suction is still good!They have amazing customer support because when i received my package i only got 2 so i message the company an within 24 hours they were sending me my insert.

### ⭐⭐⭐⭐⭐ Works Well
*by L***F on May 29, 2023*

Purchased these for my MomCozy 12 pump and they were compatible and worked well.

### ⭐⭐⭐⭐⭐ I wish I had these sooner!
*by R***L on June 3, 2023*

These are amazing!!! Last baby, I was so discouraged by all of the standard size flanges and spent so much time and money finding pumps/parts that would fit me. These make it so I can use any pump of any standard size!
