It's not: disable service screen-it's there every time, can't transfer distance traveled from previous computer, has two wheel size but only one bracket
probably my 5th computer sigma, worst of all, I chose BC12 because I expected the same sigma, unfortunately it doesn't happen, a) the mount is bigger BC12 can't be transferred to the old one b)the battery is suddenly bigger 2450 too, it's not a common cell, if I knew that I wouldn't buy it
