Among the many breast pump brands, Medela and Ameda share a solid background in medical devices, but their commercialization is much faster than Ameda. In 1983, Medela was the first to pull the breast pump down the altar of "medical" and put its classic manual base breast pump into the hands of millions of mothers, with a good reputation in the United States, Germany and Asia. Instead of the expensive and bulky image of traditional medical breast pumps, Medela launched the Mini Electric and Pump in Style electric breast pumps in the 90s, which greatly solved the needs of working mothers, and the Swing breast pump launched in 2005 is still the first choice for mothers when buying breast pumps.
 
Medela found that babies suck from fast to slow, with fast sucking stimulating the nipple and a slow and deep feeding action after the formation of a milk show, which can express most of the milk in the breast in a shorter time. Medela's unique dual-rhythm technology is a perfect replica of the baby's natural feeding process, which stimulates the breast with a gentle and rapid lactation pattern, followed by a slow, powerful pumping pattern. Although the dual-rhythm technology is not as highly customized as a piston breast pump, it can be used directly by new mothers who do not understand the laws of breast milk production without groping.
 
Among the electric breast pumps on sale, Silk Rhyme, Silk Wing and Feiyun are all diaphragm breast pumps equipped with dual rhythm technology, but there are differences in the main engine power, connectors, etc. From the outside, Silk Wing and Silk Wing are the same, both are very round and small, but the connector of Silk Wing is much easier to use than Silk Wing, eliminating the overflow valve and silicone anti-spill membrane that are easy to damage or lose, and replacing it with a silicone gasket that is directly integrated into the connector, which is much more convenient to use or clean. Moreover, as a bilateral breast pump, the host power of the silk rhyme wing is stronger, and the one-to-two catheters can also be easily modified into a unilateral mode, although the price is nearly 2000 yuan, but it is more worth starting than the silk rhyme of 1499 yuan.
 
Feiyun's connector is no different from that of Silk Wing, but the overall configuration is more high-end than Silk Wing, the main unit is more compact and silent, and has an LCD display and intelligent memory mode. If you use it outside, Feiyun's rechargeable battery can last for 3 hours, but the price of nearly 3000 yuan still discourages many users.
 
If you go out more frequently or need to carry milk to work, the Pump in Style series, which is popular in the US market, is worth buying. Pump in Style is a very practical on-the-go pumping kit that includes a breast pump, accessories, ice rafts, ice packs, and a storage bag. The breast pump can be attached directly to the included pouch so you can pump without having to take it out. After pumping, the breast milk is kept fresh directly with the included ice pack, which greatly simplifies the tedious pumping process and does not make it embarrassing to pump outside. However, the Pump in Style breast pump is not very good-looking, and it is slightly louder, and there are three storage bags to choose from, all of which cost around $300.
 
When it comes to piston breast pumps, Medela's newly upgraded Sonata range is almost the most beautiful piston breast pump on the market. Although the fuselage is relatively large, it is round and durable, and the semi-inclined silver control panel is also quite textured. In order to reduce the difficulty of operation, Medela does not offer multiple gear settings like Ameda and Ador but directly provides users with two modes of power saving and comfort, eliminating the need for learning and exploration. In terms of user experience, the power-saving mode is not much different from the diaphragm breast pump, while the comfort mode takes full advantage of the piston breast pump's ability to slowly reduce the suction power, making the pumping process smoother and smoother.
 
In addition, the functions of the Zhiyun series such as one-key pause, countdown, mute and so on are also very intimate, and after connecting with the mobile phone through Bluetooth, you can also record the pumping time and milk volume at any time, which is convenient for users to plan the next pumping time. The connectors of the Zhiyun series have also been newly upgraded, and the air and milk are isolated through a bowl-shaped film, which has a better anti-backflow effect than Silk Yun and Silk Yun wings. However, the price of the Zhiyun breast pump is as high as more than 3,000 yuan, and the price of Amazon in the United States is also 349 US dollars, which is almost the most expensive breast pump on the market.
 
Despite the poor backflow protection, Medela's connectors are very flexible and easy to use, and the breast shield can be split with tees, making it much easier to use with a breast bra than brands such as Spectra. If the standard 24mm breast shield is not the right size, you can simply purchase a different size shield and do not need to replace the tee fitting. As a result, many users like to connect Medela connectors to breast pump mainframes such as Spectra, and a large number of unofficial adapters have emerged, which can be purchased at Amazon in the United States if needed.
 
In terms of manual breast pumps, the Medela Harmony and Yun hand breast pumps can be rotated 360 degrees to suit a variety of pumping positions, and can also achieve two pumping modes by pressing the short and long handles, priced at 258 yuan.
