Original product with excellent quality as expected by Shimano products. Sent in an box as shows as other pictures and delivered in ten days. If you are in doubt regarding the power delivery of these BR-M6120, it's the same brake as the MT520, what it changes is only the type of the clamp of the lever, for this there are excellent reviews, I think it's the most powerful upgrade regarding price/performance ratio.
