    Does not fit Momcozy S12 pro
  

*by K***I on Reviewed in the United States on 21 November 2023*

Do not buy if you are looking for an insert for the momcozy S12 pro. It will not fit. It is too small to fit in the insert and slides right out. Also, I did not read that it was non-refundable so if you have the momcozy S12 pro, save your money :)
