Recommended model: Calypso series
 
Amdo has a deep relationship with Medela and AMIDA, also from Switzerland, and its founder, Werner Krähenbühl, is one of the founders of Medela and has served as Ameda's global CEO. Before getting involved in breast pump products in 2010, Anduo had acquired Ameda's medical suction technology and perinatal medical devices for several times, and also integrated some of Ameda's international marketing resources for breastfeeding aids, and its Calypso series of breast pumps won awards such as Bizzebaby Awards and Kidsgo Reference after its launch.
 
The Amada Purely Yours series adjusts the suction power and rate through two infinite knobs, while the Calypso series combines 8 suction and 8 speed levels through the up and down buttons, and then superimposes 64 pumping modes, so that every user can find the right setting according to their needs. According to the official advice of Anduo, first combine 2-4 levels of suction with 6-8 levels of frequency, and wait until there is milk secretion or milk bursts, and then combine 4-8 levels of suction and 2-4 levels of frequency to efficiently express milk.
 
Similar to AMEDA, Ador connectors isolate milk and air through a vacuum-sealed silicone air barrier to prevent the milk from the bottle from flowing backwards into the hose and causing damage to the motor, as well as secondary contamination of the milk. Calypso series is divided into unilateral and bilateral, the main engine shape is slightly different, but there is no obvious difference in power and adjustment gear, both support 6 No. 5 batteries for power supply, the price is 1499 yuan and 1699 yuan respectively. In terms of accessories, Anduo is not stingy, and the unilateral model comes with two sizes of breast shields of 22mm and 26mm, as well as a refrigerated ice pack. The bilateral model comes with more 28mm and 31mm breast shields and 26mm massage soft shields.
 
Ondo's manual breast pump is also available in a variety of breast shield sizes, so users with special nipple sizes don't have to worry. The handle of the Anduo manual breast pump is longer than that of the general breast pump, and there are multiple angles to choose from, which is comfortable and labor-saving to operate, and the price is 199 yuan.
