This is a complete scam.After purchasing this item and using it for 4.5 months it just died. This people refuse to help and i am starting a claim right now. Not worth it, Apple Store told me repair cost $970-$1280.Morher board - Ligic board went dead.Save your money, time and just buy from Apple.Complete waste of money. Small shop from NJ think they can scam people  Rebuilding Apple products. Complete Amateurs !!!!Happy Hollidays scammers !!!!
