Avent Isis Manual Breast Pump Review

I love the Avent Brand.  I have been please almost all of their products from the plain old bottle to the pacifiers and from the microwave Sterilizer and nursing pads.  I love Avent.  I don't, however, like the Avent Isis Manual Breast Pump.  It is the only breast pump I've ever used so I'm not real sure if this is normal for a manual or not, but it was such a hassle to get going.  Naturally, when you breast feed, you tend to pump only in some special circumstances (unless you work from home and you'd be advised to stick with a hospital grade pump anyway!)  This pump was so much to take apart, clean, dry, reassemble and use to pump again.  It was difficult to see if all the parts were in there properly so I would start pumping again, and it wouldn't "suck".  So I'd have to take it apart and start over again to make sure I had it all in place.  It was very frustrating.  Then there were many times it seemed to pinch me.  The suction just seemed so uneven that it would pinch rather than pull out milk.  Also, it didn't have much suction power to it at all.  It was more money that I would have paid normally, but I needed one and chose I brand I loved.  I ended up using it maybe 4 times and put it up for good.  It was a terrible waste of money and I would advise anyone to just pay a little more and go for an automatic pump!
