Hi,

With breastpumps, you pay for what you get. if this is your first baby, you will get use out of a pump like the "swing" with subsequent babies. The motor on the mini electric has a limited lifespan. The mini-electric is also very noisy. In comparison to other baby "stuff" we buy the cost of the pump is not enormous. I would go for the best you can afford.

I agree with this 100%, and I've owned and used both the mini electric (with DS1) and the swing (with DS2)

I actually find them both loud - mini electric was louder though - but thats compared to the commercial/hospital pumps

I found the swing to be slightly gentler than the mini electric too.
