This is a very good quality ramp.  It is lightweight, well constructed and telescopes easily.  It does flex a little when my 85# dog bounds up it but both ends sit firmly in place and it is quite stable.  I previously had a slightly shorter ramp made by a different company which was entirely plastic, more rigid, narrower, heavier and difficult to extend.  The original cost was about the same for both and this XL Pet Ramp is a far superior product in my opinion.  I do cover the ramp's surface with throw rugs because my dog doesn't like the abrasive material but don't find this troublesome.
