    OWC Warranty
    All OWC Memory is covered by an OWC Memory Lifetime Limited Warranty including the OWC Lifetime Advanced Replacement Program and 30 Day Money Back Guarantee! This warranty shows our commitment and confidence in the product we sell. OWC certifies and tests ALL OWC memory to ensure that this memory meets or exceeds the specifications for those systems a module is listed as being correct/compatible with. Unlike the competition, OWC owns and maintains our own lab that includes nearly every Apple/Mac model we list compatibility for.

    In addition to the long testing every OWC module undergoes before shipping (most just short test if they test at all), we also continuously batch test modules in the actual machines. You can count on OWC to consistently deliver the top quality memory products you need, correct for your system for a lifetime of reliable operation.
