My workshop has a four-inch drop from the garage. This ramp is perfect. It is very sturdy and feels solid when you walk on it. I had to trim its width a few inches which was not nearly as hard as I thought it might be (I used a multi-tool and it cuts like butter.). It grabs to the flooring with no skidding. As others have said, the rubber smell is strong and it hangs around longer than the two days suggested in the ad. Overall, this is a great ramp and I sense it will last for many, many years.
