Much better than I expected. And this was a thin ABS plastic frame structure covered with what is essentially a floormat, like I see for sale at the store that sells stuff 'dirt cheap'. No Sir. These ramps are made out of THICK rubber material. Essentially it feels like what hockey pucks are made from. Virtually indestructible, for the most part. These are something that will be handed down for generations. I don't imagine them ever wearing out. I was really puzzled when these arrived, and my mate said that the mailman delivered a super heavy box. I couldn't figure out what it could be, as I didn't order anything heavy, or so I thought. I am just using these to get my snow blower & lawn mower up over a 4 inch curb. They are overkill, to say the least, for that application.
