Perfect fit to the machine.

Super easy to use, great quality and fit my Medela (Pump in Style Advanced). Pumps are super expensive, especially if you aren't sure you are really going to need/be able to successfully pump, or not. That all said, I had a cheap, single-side pump for my first daughter and it was not convenient/didn't work as well as just hand expressing. In come baby 2 and 3...I wanted to make sure I had a good pump (and thr band...get yourself the band that holds the pumps...) so I could give it a real shot. My sister actually gave me the mechanical part of this pump (literally just the motor in the knapsack) and I was able to buy these spare parts. If you can find a good used pump this way and replace the parts I think this is the way to go...reduce a bit of waste here and if you don't end up pumping (why did autocorrect change that to pimping? If you don't end up pimping like you thought...lol) like you thought you would, well at least you didn't break the bank on a $400 pump. Im not sure if my cup size matters here but I am a C-34 when nursing (regularly closer to a B-34). If you do find that pumping is for you, I found that purchasing an extra set of these was a great idea. That way I didn't have to stress about washing/drying/sterilizing right away. It's the little things that make life a touch easier:)

Very fast delivery. The estimate said a week and I got it 2 days before the estimate which was awesome. I was a bit surprised to see that the flange and connector was one piece. Didn't read the product description well I guess lol but it works really good. I have a medela pump in style advanced. Fits just as it should plus Cheaper than buying directly from medela. Would buy from again. Love it

Ok, the quality is not great

These work perfectly I love everything about them they work just as good as the medela ones for less them half the price.. Plus they got to me super quick! If I ever had to get replacement parts again I would choose these again :) I definitely recommend to buy them :)
