Good enough quality for the price. They don't seem to last as long as other, more expensive brands. You get what you pay for.

good price seem to wear faster than more common brands. when new they are thick and have a flat surface to them that worked to clean off weld table while using the grinder more flat like a palm sander worked good for this.
