Purchased new 4 years ago and used for about 2 months. This is a rechargeable electric breast pump. It can be used on both breasts simultaneously. Operation has been confirmed. For those aiming to exclusively breastfeed with their first child, I recommend using this to stimulate milk production during the newborn stage! I don't naturally produce a lot of breast milk, but thanks to this product, I was able to exclusively breastfeed both my first and second children. I think it would have been difficult to exclusively breastfeed without this pump. I repurchased the same model for my second child after getting rid of the first one when weaning my first child. #ExclusiveBreastfeeding #Electric - Brand: Bellababy - Model Name: BLAB015-02 - Included: Instruction manual, all parts - Features: Rechargeable, digital display, multiple modes - Colors: White, Blue - Quantity: Set of 2 Thank you for looking.
