Okay, so I've been using the Momcozy S9 for about a month now and here's my honest take:

First off, the hands-free thing is LIFE. I can finally make coffee while pumping! No more being chained to the wall like some dairy cow. The suction is decent - not hospital-grade strong, but gets the job done if you're patient.

BUT... it's kinda bulky? Like I feel like Dolly Parton when I wear these under my shirt. Not exactly 'discreet' as advertised unless you're wearing a hoodie three sizes too big.

The battery life surprised me - lasted through 6 full sessions before needing a charge. But heads up: you can't use while charging which is annoying when you realize it's dead right when you need to pump.

Cleaning is my least favorite part. So. Many. Tiny. Pieces. I swear I spend more time assembling/disassembling than actually pumping sometimes.

Would I buy again? Yes, but only as a secondary pump. It's amazing for car trips or quick errands, but my main electric pump still does better for full emptying sessions.
