I bought this product because I wanted something to help pump bottles for when I would go out with my daughter. My main focus is to breastfeed and use pumped milk for outings.
I didn't want the mechanical product because I did not plan to pump all the time.
This product fits my needs. I pump about only once or twice a week and it helps me produce 2-3 bottles of milk for my daughter for places like Church or the Grocery store.
It takes me anywhere from 20 minutes to 40 minutes to get about 5-7 ounces of milk.
It can become cumbersome and tiring on the hands and wrists which makes me happy that I only do this a few times a week.
I do like the manual aspect where I set the pace and feeling of how I pump my milk. I also use Dr. Browns bottles instead of the medela bottles that came with my product.
Overall, this is not for anyone who pumps frequently as you will not like pumping.

Perfect if you want to pump occasionaly! Works well, small enough to bring it in you purse if you go out... I found it very expensive for what is it exactly but i don't regret my purchase at all!!

I wanted a manual pump for the occasional pumping I would have to do. I find that the medela does a decent job and I am able to pump quickly and effectively. I would recommend that once your milk supply is thoroughly established and your baby is sleeping longer through the night that you buy the bigger sized bottles as the pump/bottle seal tends to leak a little when you approach the capacity threshold. I like that you can also buy the bags that will allow you to directly pump and freeze.

I breastfeed exclusively but wanted a pump for the occasional times that I would like the grandparents to take care of baby, or if I wanted a drink or two. This pump is so easy to use and so effective. I can pump 5oz in about 10-15 minutes. All parts are easy to clean and assemble and it is not uncomfortable to use.
