Extremely long cable. Thrice the length of my original mi cable. The diameter of the cable is so thick that the other cables look very timid and thin in comparison. Seems very much solid and big. Since it's a thick cable, it won't be so flexible to roll it nor bend it for storage. Got it as a spare cable, so checked both cables once, and found it charging my redmi mobile as my original cable's speed, if not a little faster. Can't comment about the durability, but I like these cables. For Normal use, 3 ft cable would be Ideal. Overall a good usb cable from Amazon.
