Momcozy S12 Pro – actually leak-proof or nah? Be real with me, moms

Hey moms, need some honest feedback here. I've been eyeing the Momcozy S12 Pro but don't wanna drop that much money without knowing the real deal.

Quick background: my LO is 3.5 months. I have medium-to-high supply but clog super easily, and my right side ducts are still pretty narrow. I've been using a breast pump a friend gave me, and halfway through pumping, if I need to bend down to grab something or hold the baby – boom, my pants are soaked. Then I have to change into sleepwear after washing up. So annoying.

Lately I keep seeing reviews saying the S12 Pro has double-sealed design so it won't leak even when you move around or do chores. Sounds tempting, but I'm not ready to blind buy.

So I'd love to hear from real users:

Does it actually NOT leak when you lean forward or lie on your side while pumping?

The stimulation mode's vibration - is it okay for someone like me who gets clogs often? Or will I be sitting there forever with nothing coming out?

How many sessions do you get on a full charge? My commute is long, and I'm worried I won't have enough juice to finish pumping before evening.

Also, is it easy to clean? I'm kinda lazy - are there a million little parts to take apart?

Honestly, for such price I need real talk. Please share your experiences - would really help me avoid another messy situation.

Thanks, pumping moms!
