I just got the new Air ones momcozy pumps instead of the M5. The M5 worked for me for 3 months helped me get my milk supply up! Then it wasn’t pulling enough out unfortunately. Then I got the new Air ones and the settings on here. Is helping bring the milk supply I lost! I love how I can control everything on my phone. It is very nice 
That’s a great feature I am going to upgrade my pump soon and this is helpful!
