Difficult to maneuver and carry 2 babies in the car seat once then turn 6mths.they've become too heavy at this point to keep lifting them in the car seat from the stroller into the car.the straps are not easy to adjust. Complete nightmare! The stroller is bulky and takes up the entire trunk. I contacted the seller VM Express to do an exchange for a separate car seat / separate (no combo) stroller. And they refused to do a exchange or return.
