I purchased the breast pump two years ago and have only used it 2-3 times. It has been sterilized and stored. The baby bottles and nipples that came with it are unused. I used the microwave sterilizer, which I received from someone else, when traveling or staying overnight. Since I mainly used soaking sterilization, I didn't use it very often. It may have some minor scratches. Please refrain from purchasing if you are overly concerned about this.
