I had to return a telescoping pet ramp I got through Amazon because the scratchy, ping pong paddle surface didn't work for my 30 pd dog.  She literally slipped and left scratched marks on it.  This one has ridges that are close together and the surface feels like a synthetic rubber.  I set it up and put a couple pieces of kibble at the top of the ramp set at a 45 degree angle and my 8 year old dog scrambled right up it, ate the kibble and laid down on it.  I had to tell her "table" to get her up and onto the table.  She had knee surgery earlier this year and this would have helped a great deal with the car and the grooming table as I have a bad back making it a challenge to lift her that far.  I don't need it to get her down but may try it to get her ready for the back of the SUV.  It is 2.5 pds heavier than the other and the sides are relatively thin plastic as opposed to the fiber glass with the telescoping one.  The box states that it weighs 18.5 pds which differs from the description a bit.  This one is harder to move around and there really is only one length.  It's rubber feet left a mark on white berber carpet that the vacuum removed. A friend of mine has this ramp and has used it for a variety of other uses.
