Has anyone used breast shells to collect excess breastmilk? I find myself constantly leaking!

Breast shells can only collect a small amount of breastmilk, why not consider using Haakaa pump? Haakaa is a New Zealand brand and the pump is made from food grade material, the same material used to make pacifiers. The pump can suction on to your breast hands-free and collect up to 100ml of breastmilk. It is available in Singapore for $18.90 at www.greatvaluebuys.com
