I bought this pump thinking that an electric one would be better than a hand pump and that a double one would also be faster to use. I was wrong. When I purchased this as a first time mother, I really did not know what to expect...I found it uncomfortable and after two weeks - one side broke. I received another one and in a month the same thing happened to the second pump...one side broke as well. I gave up on this pump and bought the hand held Advent Isis. I am so thrilled with the Advent hand pump - it is unexpectedly easy and comfortable to use. A good breastpump makes breastfeeding easier - get a hand pump.
