We bought this for our year-old, 16 lb puppy who wants on and off the bed every five minutes. I like the length better than many shorter indoor models because it results in less of an incline. First off, we found our puppy slipping on the hard surface even though it is textured, so I folded a blanket to form a liner, tucking it under at each end, and that problem was solved. Our trick to get the dog to use it was to take a favorite toy and move it slowly up the ramp. The dog followed the toy. Same with going down. Still, it took a few days before he would automatically use the ramp. I'm sure that each dog (and each owner) is different but I thought our experience would be useful to others. We are very satisfied with the ramp. It is well made and  easy to move when necessary.

Good length, light weight yet durable, folds.
Too slippery without a liner - no big problem.
