Pros: Adjustable, nice carry bag, interchangable parts with the manual version
Cons: Lots of parts, sometimes don't fit together snugly
Bought this one because it was one of the few that will work on both 110 and 220 volts. I used it twice a day for 9 months and the parts don't fit together as nicely as they did at first. The gummi "Petal" cone really doesn't fit well anymore and sometimes affects the suction. Hoping it holds up for baby #2. Some nice words for Avent, though- while travelling I lost the inner valve and couldn't find a replacement in a store (small town). I called Avent and they sent a 6 pack replacement to me for free, with fast shipping.
