Title: The worst on the market!!!
Review: After the first time I used the pump the adapter stopped working. I called First Years and they asked me to send it back on my dime. I asked them what to do mean while. They suggested using batteries. I tried that for a couple pumps but the batteries had to be changed after every pump. This was the biggest waste of money. Purchasing this has taught me one great lesson. Do you reseach before purchasing something of this great importance. I have since thrown the peace of trash in the trash. I never sent the adapter back to First Years. To do so would cost me another $10 after using my Fedex employee discount.
