I purchased the VEVOR Impact Socket Set 1/2 Inches 26 Piece Impact Sockets, Deep Socket, 6-Point Sockets along with the VEVOR Impact Socket Set 1/2 Inches 19 Piece Impact Sockets, Deep Socket, 6-Point Sockets, Rugged Construction, Cr-V, 1/2 Inches Drive Socket Set Impact 3/8 inch - 1-1/2 inch to meet my impact socket needs. I think they are built of heavy, strong steel and have stood up to any job I have thrown at them. The were much more affordable than other brands and better quality too.
