Bought this for my daughter who is trying to becoome an accomplished pitcher. We use it to be aboe to throw anywhere we can get a flat 40-43'. The spikes are heavy steel and provide ample securing to the ground. However, the mound is starting to chew up on the edges and flake away and it hasn't been used 'heavy'. I noticed that the Youth mound we bought a year ago that was used heavy last year and is mounted to a 'takeoff' mat is still going strong.
