Garosa Insulated Bottle Bags Editorial Review
The USB Milk Bottle Warm Heat Keeper is a convenient accessory to keep a baby's milk or water warm. It can hold 150-330ml bottles, and it can be used on both glass and plastic bottles. However, it is essential to understand that this warmer is not meant to heat cold milk, but rather to keep warm milk warm. It is not suitable for breast milk from storage bags. It can work well with power banks, but it is not cordless. Some users have experienced problems with the product. Some say that it didn't heat the bottles, didn't work on glass bottles, and didn't keep hot water warm.
