1. Function: In addition to the basic health monitoring function, Yuyue also provides advanced functions such as sleep monitoring and blood oxygen saturation detection, while Mikael only has the basic health monitoring function, and Yuyue's products have more functions.
2. Technology: Yuyue adopts advanced sensor technology and algorithm, which can accurately monitor users' health indicators and provide personalized health advice. However, Michael's products are technically conservative and lack innovation, while Yu Yue is more prominent in technological innovation, so Yu Yue is good.
