I can not speak highly enough of this pump, I bought a single one just to try it out and after using it a few times I ordered more.
Great battery life, great suction, big cups without being super bulky. Its comfortable and easy to disassemble for cleaning. It comes with inserts for different nipple sizes, it has so many different settings that I first thought of as overkill but am now so grateful for.
I have nothing negative to say, it's the perfect hands free pump. 10/10, 5 stars.
