I think the Avent bottle sterilizer is great! It allows easy, fast sterlization of my bottles, and today I am going to use i to sterilize my pacifiers and breast pump parts as well. If you want it to sterilize the number of bottles it claims to sterilize, its like a jigsaw puzzle to try to fit all the pieces in it, you definitely have to follow the diagram the first time, but it did fit al 6 4oz bottles in it with all the parts, so in 4 minutes I had it all done! The fact that it is much quicker than boiling water is awesome. I think this is a great product for busy moms and dads and give me peace of mind that the bottles are cleaner than if I had hand washed them-- and in less time, you can't beat that!
