I'm mostly happy with my pump. Positives: super fast delivery, good quality materials and convenience of being hands free whilst pumping! It pumps really well, no discomfort and straightforward. Battery life is decent. Negatives: the pump leaks, A LOT, if you bend forward at all which wastes so much milk and your clothes get soaked. I have double, triple and quadruple checked all the seals and attachments and instructions, and this seems to just be a design flaw or I'm super unlucky and received a defective one. I now have to make sure I only pump whilst wearing my house clothes just in case. Also there is no warning when the battery us due to die, which is annoying, so hopefully something they will update with future models.
