I absolutely loved this for sitting or standing and nursing. It collected very well without overfilling. I did need to lay down a few times and wished that I could lay down with it but I couldn't. It does have the ability to suction to the breast, and pouring it was a bit hard. I dont know if there is another way to pour it out of the collector orher than opening it, and that was scary for me, I didnt want to loose my milk. Otherwise cleaning was easy. Thank you Ceres Chill!
