I tried it today. It's very good, especially the packaging is very solid and perfect. The layers are well packaged. It is worthy of the brand. The accessories inside are also packed in separate sealed bags. The atomization of the machine is very fine, and the time is shorter than that of the hospital. The key is that the atomization is very clean and the noise is not big. It saves the trouble of running back and forth in the hospital. It is quite hygienic to prepare one at home.
