I was.given this at the hospital and for a few days this was awesome. Pumped like a pro but within 2 days of use the suction just gave out. The info basically said the little cheap rubber part in the middle will give out and then you have to replace it. Which woukd be fine not for two days of use!! Also it will make uour hand tired so great exerciseof sorts. If you use it sparingly its great but i had just got into a cycle with feedings and it gave out. Too expensive to replace.
