Query: It's slow and noisy

I have been breast feeding/pumping for 5 1/2 months and was using a double, electric pump. I bought the Isis because of the small size for traveling and because of the good reviews it got.My advice for someone looking to buy it for travel - don't do it. It takes 45+ minutes to express from both sides because it's so slow. The silicone insert is extremely 'squeaky' and extremely annoying. I also felt like I was going to get carpal tunnel in my hands from the pumping action.I also had a very difficult time getting the suction quite right. I wanted to cry when I used it the first couple of times.
