I had to use this set when my milk didn't come in. It was easy to clean and use, especially when sterilising bottles anyway. I did find that my hand tired fairly quickly when using it, which was an obvious disadvantage. It worked well for the odd occasion when I needed a portable system, but I wouldn't recommend it for full-time use. (It came as part of an electric Ameda pump, which I hired and used at home for a while).
