Avent Isis Breast Pump
An all new design which is said to be capable of expressing the same amount of milk in the same amount of time as an electric pump, comfortably, and with very little effort. The bell has "petal massagers" which stimulate the let-down reflex. The soft bell and silicone diaphragm combine to create a perfect vacuum so there is a continuous suction and milk extraction. You can duplicate your baby's rhythm of suckling with the handle motion every 2-3 seconds. The motion of the handle is butter smooth! This Isis pump is one of the best quality products I have seen.
