Changing breast pump for better results

Hi Mummies, I am thinking to change my breast pump from Pigeon gomini to some other pump. Reason being less production from Pigeon. Every pumping, I can only get 40 ml out and if I handexpress, I can get 60 ml more. This is making me think if the pigeon pump is not good so May be I need to change the pump. I have tried multiple flanges and still no improvement. Anyone experienced this ? Did changing the pump lead to better production ? #firsttimemom #pleasehelp #FTM
