My dog loves it! Took 30 minutes to build. As is, the ramp was very slippery and my dog couldn’t get up it. I bought non slip fabric at Lowe’s and used a staple gun to place over ramp. He can now go up and down as he pleases with ease. I also used the fabric on parts that touch the wood floor. Now The ramp does not move or scratch my floors. Without the non slip fabric I would have returned as it’s too slippery. Four stars due to my extra work and extra 40 at Lowe’s for the non slip and staple gun. It gives my dog freedom!
