It looks either horrible or very funny looking on (depending on your sense of humour). I loved it because if freed both my hands! I could email, use my phone, comfort my baby or even feed/change the LO with the 'free' breast and not worry about the pump/bottles slipping ect. as I say, life changing. Worked really well with the Mendela symphony pump.
I didn't buy it in HK because I couldn't find it. I just bought it directly from the manufacturer in Canada and paid international shipping. I bought 2, so that whilst one was being washed the other could be used. Works a treat!
