The products offered by Shandong donge steel ball ...

The products offered by Shandong donge steel ball group co.,ltd are of average quality. I have used their steel balls for several projects, and while they get the job done, they are not outstanding. I appreciate the variety of sizes they offer, but I wish the overall quality was better. The customer service was acceptable, although I did encounter some delays in receiving my order.
