this be a comfortable breast pump that perform just as well or better than a Medela Symphony . we choose a dual breast pump for convenience and this unit do not disappoint . the comfort for mommy 's nipple be the advantage here , plus the pump not only pump the nipple area but express the breast like a baby would . the pump memory feature be a big plus too , you can adjust the strength and speed of the suction . the only knock that we have with the unit be that when put the breast pump down after pump , the bottle can tip over . just use the lid to hold the bottle or have some cup to put the bottle in after pump . the other thing be that there be alot of part to sanitize , but after a while you learn to disassemble\/reassemble pretty quick . it be worth the trouble though , comfort to mommy and performance outweigh this minor inconvenience . pro : - incredible value - mommy 's comfort - adjustable setting with memory feature - perform the same or equivalent to medela version con : - too many part to clean\/sterilize - bottle can tip over if you do not use the lid to hold the bottle after pump in the end , we would definitely make the same choice again , even with the con . I hope Philips will make the bottle holder for the next gen and use less part . : -rrb-
