Dedicated sterilizing case for baby bottles, breast pump set - Brand: Milton - Dedicated container: Sterilizing case for baby bottles - Color: Blue - Accessories: Tray Breast pump Manual: medela Automatic: Overseas brand For the manual pump, I repurchased it because the handle broke, so I have two sets of containers. For the automatic pump, I purchased it from SEHIN, and there is no instruction manual. When you press the power button and then the second button from the left, there are three menus to choose from. You can select the strength with + and -, but I used the strongest setting. For all products, the rubber parts have slight yellowing, but there are no scratches. All items have been sterilized. Thank you for looking.
