I own both the medela pump in style adv and ameda's puelry yours pump. Ameda's pump is better than medela. And durability and reliability are great. I am a working mom so I pumped a lot with baby #1 and am doing same with baby #2 already have a freezer full of milk. This pump has lasted since 2008 with pumping daily 5 days/week (I breastfed baby #1 for 18 months) and it is still going great I'm using it now. Why ameda is superior to medela: 1) NO MOLD growth milk cannot get into tubes. See below. After I found mold on my medela pump I went out and bought an ameda pump right away. 2) about half the price as medela if you just buy the pump and not the bag etc. 3) the ameda pump is easily freestanding, also has nice slots on the pump to hold your pumped milk in bottles. If you remove the medela pump from the backpack or bag you'll see the pump casing the medela pump has holes in the casing around the pump so you don't really want to take it out of the bag and nowhere to put your pumped bottles so they don't fall over. Medela knows about the milk in the tubes problem in fact there are instructions about this in the booklet that comes with their pump. Well, I got milk backed up in the tubes more than once despite following the instructions in the manual. Then I had to stop pumping and dry the tubes out. No more pumping that day. And, to my horror, despite running the MEDELA pump for a couple of minutes after every pumping as per instructions, and drying out the tubes if they got milk in them, I opened the faceplate of the medela pump one day and found MOLD growing on my medela pump. That was it, I bought an ameda pump and have never gone back.
