Sangat berguna, sangat tahan sejuk sehingga 8 jam..saya amat berpuas hati dengan vcool bag ni.. Amat mudah dibawa dan tahan lasak daripada segi jahitan dan lapisan fabrik supaya kekal sejuk.

V-coool is good in keep cold. The function of keep cold is very goof but the volume is too small.
Even there are 2 compartment to separate the ice brick and pumping machine, but it is hard to fit in my Spectra M1.
The keep cold compartment can only fit in maximum 4 bottles of breastmilk with a mini ice brick.

V-cool Bag的耐冷是不错的，不过这款的cooler bag 的容量不是那么的大，放不下其他的东西。
