An adjustable wrench is rarely the best tool for the job, but sometimes it's the only tool available or the most convenient. This wrench is manufactured in Spain by Irega, a specialist manufacturer of these products. The jaws are firm and don't rattle. The setting wheel runs smoothly and has sufficient friction. Beautiful scales are engraved along the underside of the jaw opening. I'm very picky about my tools (almost all are high end German or American tools) and I'm impressed with the quality of this wrench. Bought three in different sizes.
