this product be outstanding ! we use it to take we 2 year old and he car seat across the country and it work like a charm . it even allow we to take we son off a airplane and through a airport sound asleep ! he enjoy he `` stroller '' and would ask to ride in it as soon as it be hook up . it be a breeze to hook together and be a easy matter to take apart and reattach for security check . it be important to note that it only work with a latch system car seat . Ours be a older Britax Roundabout and it work perfectly . we be ask several time by airport personnel , other mother and random people where we get the product . over six year and several trip with we child , we have try a car seat bag -lrb- the strap break -rrb- and a back-pack strap thing -lrb- then we still have to carry we child or a stroller -rrb- and both be outrageously expensive and very disappointing . this inexpensive product be a true find and I intend to tell every parent I know travel with a car seat all about it !
