In terms of performance, the MacBook exceeded my expectations. It runs smoothly and efficiently, handling multitasking and demanding applications with ease. The battery life is surprisingly good for a refurbished model, lasting me through a full day of work without needing a charge. One of the aspects that truly impressed me was the customer service provided by JemJem. They were responsive and helpful throughout the purchasing process, addressing all my queries promptly. Additionally, the warranty and return policy provided me with peace of mind, knowing that I could rely on JemJem in case of any issues.
