The double electric pump is just perfect! I started pumping quite late on due to retuning to work wanted to build a stash for baby when they are at nursery. I wasn’t sure if I would get much out but that’s not the case and manage to get on average 3.5-4oz (both boobs). I love that it comes with a selection of flanges, spare parts and that it can go in the dishwasher. Very happy with this pump and works on big boobs too. I would recommend it to everyone!
