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:)

I got a set of these and was having problems with the suction so I contacted customer service with my questions and complaints. I was originally concerned with the fit. They got right back to me saying that there may be a problem with the product since the suction shouldn't be a problem, so they asked for the special item production date which was on the horn part. I gave that number to them and the said that they would ship me another set in the same size to try as well as the 19" 24" and the 22" inserts. I couldn't believe how fast and personal the responses were. I'm talking like responding at 2:00 in the morning to my emails back and forth! They are based over seas but have a local branch here in North Carolina which is nice for contacting purposes. The new product worked perfectly. I even did some research on the company and the testing they did on there products they went through to pass FDA guidelines since the provide copies of the tests on their website. Everything checked out as being legit and official. This a a great new company producing a highly affordable quality product with wonderful customer service. Buy this instead of the name brand. If you have a problem with fit or quality contact them and they will be sure to make you happy!!!

Excelente producto, universal y de buena calidad. Incluyen varias membranas que suelen extraviarse seguido x su tamaño. Lo único malo es que el embudo no se separa, es una sola pieza, pero una vez acostumbrándose es cómodo.
