I love this steel ball. I just got it. It's heavy and shiny just like I wanted. 3 1 2 inch diameter is plenty big and I think worth the extra 20 bucks. Any bigger than this would just be extremely heavy and not as fun. Only bad thing about it is that the chrome finish has some imperfections so it is not perfectly shiny. I'm already thinking about getting it refinished to get it shinier. Other than that the ball itself is very good quality overall.
