I would give this pump 4.5/5.
Pros:
1. Really good suction with different pumping modes. You have to try the Surge mode if you want to empty the breast fully & fast. I normally use this mode for the 1st pumping of the day
2. Heating function works pretty well for me. Warm up super fast. 👍
3. Super quiet pump. I'm surprised with this.
4. Long battery life, enough for me to pump 5 times per day with the heat on for 5-10 mins
Cons:
1. The dust cover doesn't stay well in place, easy to fall out
2. You have to be careful when pouring out the milk, otherwise the milk will be easy to spilled out
3. I think this pump suits better for women with large breast. I'm 150cm, 40kg and having cup A before pregnant so the pump looks a bit bulky on me. But I'm pumping mostly at home so it's totally fine 🙂
