Had a different brand but very similar design.
We got it for a cruise when one of our children was still in a stroller.
This was the number one most handy kid gadget we took with us. Sometimes I felt like a pack mule with all the stuff we took, but this carrier made crowded shore excursions a pleasure - our child was safely attached to us and no stroller-people collisions, etc...
Also phenomenal for crowded art fairs, the zoo, etc.... And some places do not allow strollers.
Our child slept easily in it as well - something about the rocking motion. Seemed to enjoy the adult-height views as well!
This + a compact, light weight, one-hand-open, high quality stroller are no brainer baby buys.
