This is a great product. It is lightweight but very, very sturdy. I have 2 dogs over 60 lbs. and have no qualms about these not holding up. Easy to put together and it has a rod under the front of the bottom step so easy to move around. I am going to get another set to keep in the car. I have a Suburban and the these steps go a little shorter than the top of the running board in the back so the dogs just hop right in. Before I had to try and lift them in (65 yr old female) and they hated to go anywhere. Now they love to go. So glad I found these. Really worth the money.
