I give this a one-star review because it didn't serve my purpose. I was hoping to use it in the car so my dog could get in and out of the back easier, but I didn't even take it out of the box because it is just too heavy for everyday use (my dog goes to work with me). It's also pretty large, so it would take up quite a bit of space, leaving little room for the dog; though I think it's probably the neccessary size for my car (Ford Escape). Anyhow, I'll just resort to lifting the dog, since it's less hassle and the ramp isn't much lighter than the dog.
