I can’t answer regarding the electric ones but I’ve tried the manual pump. Easy to use but subsequently after using it for 3-4 times the suction is badddddd. 🙄 Also, not forgetting that if you’re using manual pump, it’s double the time as compared to dual electric pumps. Hegen bottles & parts can all be used in UV sterilizers. Just keep the teat further away from the UV (put it at the bottom layer.)
Hegen electric is easy to use and clean, but i still prefer using medela (i got medela from my sis). I can express more milk with medela. Somehow hegen one is not strong enough, regret that I bought it. And yes hegen bottles can be sterilized using uv sterilizer (I’m using upang). All ppsu bottles can use uv sterilizer.
