I have a capsule and I really like it. I still carry Oliver to and from the car in it and he is ~7kg. Ours snaps onto the pram so if he is asleep I can leave him in it and not wake him. I cannot get him in and out of mums convertible without waking him. I also thought he was much more comfy and safe looking in the capsule over the convertible before 3 months. Our capsule goes to 12kg so based on current growth we can continue to use it to around 12 months.

Our seat instructions recommends a break after ~2 hours.
