persoanlly i cant stand the electric ones, they are loud and for me no more efficent, i did express once a day with a tommee tippee hand pump which was perfectly fine, i tried a tommee tippe electric one and a all singing all dancing calypso one but neither i found better than the hand pump, you still have to hold the electric ones so are by no means hands free, i think if you are experssing for every feed them it may be worth it but for the odd time or once a day i wouldnt bother x
