This ramp works great...  I did a couple of practice runs with my 15 year old Rottie/Lab mix in the house to get her used to it before I used it with my Mercury Mariner.  It took two tries to get her to go up from my mudroom up into the kitchen which a three step travel.  She went right up into the car like a champ without any help at all.  She is so happy she can take her car rides with my 11 year old dog and my 4 year old dog again!  I love the ramp is non-skid.  She felt secure on the trip up and the trip down the ramp.
