I purchased a refurbished MacBook Pro via Amazon from Double Dex Refurbished.  The laptop seems to be as advertised (very good condition) however the power cord does NOT work!  The only reason we've been able to use the laptop is that I have an identical MacBook Pro (same year) that uses same power cable.  I am able to charge the refurbished laptop however it is not possible to do this indefinitely.  Send me a working power cable and I'll be happy to upgrade your rating significantly.
