Warranty: 1 Year DiscTech
The product has been built, rebuilt or repaired at the original manufacturer's factory (Note we NEVER sell 3rd party repaired items, as we do not find them to be reliable enough). Often these products are extremely close to new in condition, except that they contain at least one recycled or repaired component. Failure rates are often lower on these devices since they have been far more thoroughly tested than new items. Watch a video about our refurbishing process
