I bought the pump, because I was afraid of engorgement and wanted to try whether pumping in my work at all. The rubber cap, which rests on the chest like it very much. When pumping therefore no pain. He also reduced the hole for the nipple, thus creating a good and precise size, so that the court is not sucked. For other pumps, the chest portion consists only of plastic and may be too large, so that the pumping is a little uncomfortable. The lever I find very convenient and easy to use. Clear makes pumping noises, but they are not unpleasant or annoying, I think. The bottle, which is may be a little small if you pump down both sides. The pump is easy to assemble and also dismantle and clean. The individual parts look stable. I had often in a vaporizer and everything works fine! Sometimes it happens that the vacuum does not build up, but then you just have to press it again only the rubber chest attachment and off we go again. The pump is highly recommended. I get along well with her. It is well suited when something needs to pump out in an emergency, because the breast otherwise hurts. In addition, you create a little freedom, when you can pump out a meal times and this is feeding someone else, if you eg. must go even without a child. If one pumps out every day or even several times a day I would rather recommend an electric, otherwise you get cramps in your fingers.
