I have had Babyjogger city elite for about 3 months now and am really happy! My child has had the 1 year of age (I have not tried the carrycot).
Easy to drive
Large wheels - arrives everywhere, up and down the bus, sidewalks, etc.., Goes well through the snow
Super sleep mode, but the flip-up footrest, fully reclining position and large Suflett
Adjustable handles and pockets with Small at the handle
Folding Function - very simple and can be done with one hand
Cart can be a bit difficult to access and is not as roomy, but you can attach hooks on the handle where one can hang their bags (they'll just keep track so it does not get too heavy)
The trailer is a bit heavy to carry when folded, but you need never carry it very far
I love this stroller and it is worth taking the trouble of it is a bit heavier and wider than other buggies, as it provides maximum comfort for both the child and the driver and yet is surprisingly smooth folded. It can handle any situation!
