Assuming 2 day shipping, you probably lose ~2 real hours of time, but have no working cable for at least 4 days.
- a few minutes to order the cable
- 2 days for the cable to arrive
- ~2 hours to realize it does not work, complain, initiative a refund, print a return label, and drop it off at a post office
- another 2 days to wait for the next cable.
