after trying this product, I must say I am thoroughly impressed. The crimped 2-inch diameter brush IS an absolute game-changer in the Industrial and Scientific arena. The brush provides exceptional cleaning performance on even the toughest of surfaces, and the durability is outstanding .The bristles are securely fastened and the brush itself can withstand heavy use. My only con would be that it would be helpful to have more size options available. Overall, I would highly recommend this Abrasive Brush to anyone in need of a reliable and effective tool!
