We absolutely love out Avent Sterilizer! While I wanted to exclusively breastfeed, I knew that was not going to be possible with going back to work. So once we decided on the Avent bottles, we needed an easy was to keep them sterilized. My aunt purchased this for us, and I thanks her everyday for it. I told her that if she ever need a baby shower gift, this was the one to get. We used it about 3-4 times a day! It is easy to load; and yes, it is designed to fit primarily the Avent brand bottles. Each part of the bottle has a special place that it "should" go. My husband would just put the pieces anywhere, and it worked just fine. Add the water, close the lid and microwave. It's that simple. I loved the fact that I didn't have to run a load of dishes in the dishwasher or dip the bottles in harsh chemicals. This is by far one of the most used presents that we received, and I would recommend to anyone that is bottle feeding to get one!
