I was very pleased with the ramp.  My elderly dachshund was unable to climb her stairs any longer, so I thought a ramp might work better.  It took just a couple of tries for her to get the idea that she COULD do it, and now she's a happy girl again and able to get up and down when she needs to.  

The only suggestion I would make is that it should be adjustable in height at the platform end.  I had to lower it about 4" by sawing and reattaching the legs to shorten it and lessen the angle of the ramp.  Works great now!!!
