I was really impressed by this breast pump and found it very useful as it allowed me multi task. I placed it inside my nursing bra and then used the app to control the settings. It felt comfortable and did not move about. It is not as small as it may seem but it is quiet and discrete. I had no issues with disassembling it, cleaning the washable parts and putting it back together. It is quiet, hands free and all round easy to use. I would recommend it.
