I'm sure it's fine with the dents. My concern was the holes, around the outer circle there's a staple length hole and closer toward the center it is super thinned where another 3 or 4 small nail size holes. I put 2 stars but that might just be my lack of experience in this area, it just doesn't look good for my first try at a drum.
