Any mummies bought the Fridge-to-go cooler bag to transport breastmilk from work to home? Can share your review of this product? Thanks!

I have a couple of mummy friends using fridge to go. So far only good reviews! They told me it can last about 8 hours. You will have to freeze the whole bag and buy those ice block that can be refreeze from daiso and put it next to the bottles for them to work better. Two of the blocks will be sufficient for the small fridge to go but you can get more if the fridge to go you are buying is bigger.
