I purchased this because I had a gift voucher for a baby store and was in need of a new breast pump. They only had 2 brands and this was the only electric one so I gave it a go. I really don't like it at all. It was one continues sucking motion, I am used to a medela. I found that I couldn't get much milk from this machine at all. I will be getting rid of it asap no use keeping it.
