I've used this sled twice a week for eight weeks and there are holes in the bottom of the sled now. I run on concrete and this sled isn't made for concrete after seeing the damage eight weeks of use has done to it. However, if you intend use it on turf or grass I would say that at least it will last longer.It's rather small and is not built for olympic plates. In hindsight I should have spent the extra money to get a more durable, sturdy sled, because it looks like I'm going to have to do that pretty soon.
