Looking for a pump

I’m looking for a breast pump to use with the freemie cups. I need something small and portable that I can chase kids around with all day. Maybe even something that can fit in my pocket or be easily attached to my clothes somehow. If my insurance doesn’t cover it, im ok with that. I have the medela Pisa and I hated it with my first because it’s huge and kept me tethered to the wall and I can’t do that now. Does anyone have any recommendations for a pump like this that is good quality? Thanks!!
