I bought this pump because I wasn't sure how often is actually pump and didn't want to pay a crazy amount. It's a good pump, it does the trick. Mine has a touch screen that you can adjust the suction and speed of the pumping. You can also record the volume of milk after each session if you want and can view your pumping history. It came with a convenient bag to keep all of the parts in and can easily pack it up and take it with you. It also came with two storage containers which can be used as bottles that attach directly to the pump. I don't use these for feeding, just collecting the milk. It also comes with the bar handle so you can have a free hand which is nice and two sizes of breast shields. They're easy to put together/take apart and clean. The parts are dishwasher safe except for the screen device, air line and bar handle. Overall it's a good pump for the price.
