Flimsy stopper
I love that mommed took us pumping mom's feedback and designed this new pump with upgraded features. The overall material feels a lot stronger, but the milk stopper plug at the top is very flimsy and pops right off. It also leaks or shoots right open when its tilted. If the plug were a bit thicker, this pump design would be 5/5.

Exclusive pumper!!
Im an exclusive pumping mom going on 5 months now. I originally had the s21 and tried out the s33 the last 2 weeks. They’re very similar however the s33 are more comfortable and the light addition helps for my night sessions. I get the same output as the s21 and even compared to my spectra hospital grade pump. Sound wise it’s similar to the s21 and even though they have the anti leak stoppers, they don’t close all that great. Either way I’ve never had any leakage so it’s still great in my opinion. I do prefer my s33 over the s21 but both are truly great wearables. I haven’t used my spectra in the last 3 months.

10 outta 10 recommend
Absolutely love this pump!! Strong suction, night light feature and pause button is great. Only two things that I feel like should be fixed. The caps for the spouts don’t stay in at all and the battery life is only enough for about 3 uses. But to not be hooked to the wall every pump is great.
