This has been a great pump so far! I bought it on a whim to replace the one I had when it stopped working & it has not disappointed me! Although it’s only a single pump & doesn’t come with any spare parts — it’s super easy to clean & ITS PORTABLE! You have the option of batteries or wall plug. It’s a very comfortable fit on the breast and has a large opening for nipple. Such an affordable pump, you can’t go wrong!
