I be hesitant about purchase this pump after read a number of negative review . I absolutely love Avent 's bottle though , they have be a godsend with my colicky baby , so I figure if they bottle be so wonderfully make , why would not they pump be great as well ? I decide to give it a try and love it . it be so comfortable . do not even hurt one tiny bit . I get way more milk out of it then I ever have with the Medela manual pump , as well as the Medela single electric pump . just to clarify as well , with all the negative review with the Avent pump be leaky - of course it will leak if you do not put it together properly . take the time , read the direction , and you should have no problem . it leak from the petal insert the first time I use it , because I do not seal the insert to the base all the way around -lrb- you just simply pinch it together with you hand -rrb- . after realize this , it never leak on I again . I can not breastfeed my son , so I pump for every feeding , and I always use this pump . I have wash it many a time , and it be be so durable . plus , it be incredibly easy to clean , you can get into all of the crevice . unlike the Medela pump that have tiny tubing , which i be not even sure how they expect you to clean in there ? one last thing , i have read many comment about it be loud and squeaky - just make sure the pump handle and what it attach to be completely dry . Dry = no squeak .
