my wife and sil used medela swing, recommended by a fren, she said medela r soft n gentle compare with others. My wife used mid, any above mid she said painful. my wife and sil never try others so cant compare. My brother bought usb cables so that his wife can carry it mobile and charge with power bank. If u bought medela swing, they didnt provide the cable.

IMHO varies from different individual.

hope this help
