Whilst I didn't have a I love my bear version I did have similar and it was really heavy. The carrycot was great as we had a preemie and she was small for longer than most. We never used the car seat on it (nurses orders) As a pushchair I hated it so much, I went out and bought a new pushchair. The graco was big for most places, awkward(but fitted) on buses, we lived in a flat and it was agonising, and just fitted the old fiesta boot.
It's easy to consider a travel system at first but they are generally heavy. With my second I bought a separate car seat and lightweight pushchair, better value that way.
