Hi :)
We had a milano system (capsule + pram) and loved it. I can't actually remember how long DD was in the capsule for, but it was quite a while (and she was a decent sized bubba, 8lb 9oz at birth).
I loved that I could move the capsule to the pram when she was asleep, or just carry her inside in it, rather than having to wake her up.
It was easy to install, all the instructions were printed on the capsule, and I always felt that she was safe.
We got ours from Babycity - we got the tech rider travel system, and the pram was perfect for when she was older. We have lent the pram to someone to use, and I plan to use it with our next one.
Hope this helps.
