The ramp itself is fine, but when I ordered it, and the side entry support strap, I asked on the phone if the ramp would work in my car's side door. I was reassured that it would. 
So when they arrived, I was dismayed to find that it does NOT!! It is designed for rear entry, which I did NOT want!!! 
So now I'm left with a ramp and a strap (NOT needed for this ramp, BTW) that are useless for my dog, who had a herniated disk and it's painful for her to jump into the backseat.
I will have to return both, which is a real disappointment!!
