Has anyone tried this brand of glass bottles? I know that the more popular brands seem to be LifeFactory & BornFree. My aunt was very adamant that we use borosilicate glass bottles and gave us a gift basket of 9(!) of these MOMO ones. I can hardly find any reviews on the product but it seems like a lot of babies didn't prefer these nipples that come with the bottles.

Just wondering if anyone has tried these bottles and how it's worked out for them. And now if I need to keep all my other bottles, but that'll be a different post. FWIW - I can't return or exchange them - have no idea where they are from.
