Came sooner than expected, which was very nice.  Havent yet tried it with our dog, who is a 160 St. Bernard.  Bought it so that when he gets to the point where its painful for him to hop up into the car he can still manage.  Like that its foldable and can fit into the trunk when not in use.  Hoping it lives up to the 200 weight limit as hes a growing boy!
