Review on Besrey Wearable Breast Pump, Hands-Free Electric Breastfeeding Pump, 3 Modes & 12 Levels Adjustable For Comfortable Pumping, Portable Breast Pump, Low Noise & Painless, LCD Display, With 24 Mm Flange by Eric Trask

This seems to be a much more refined option for pumping compared to the S9/S12 pumps that have the controller/pump components sitting on top of the milk storage and silicone padding, to integrate everything into one 'hump'. Being integrated into the unit comes with a good benefit - it runs significantly quieter than the S9/S12 with its exposed motor and is much more muted (it's still audible but much quieter compared to the S12 I have). One small con is that the LCD screen is less visible since your clothes can better conceal the entire unit, but the pro then is that you don't have a random little machine sticking out of the top of your shirt.
