The only difference between our plug refurbished Apple Macbook Air and a brand new one is the price. Our MacBook Air's are up to 40% more affordable and are backed by our 12-Month Plug Warranty. To ensure our products meet our incredibly high-performance standards, we’ve developed a proprietary 90+ point functionality evaluation, deep cleaning, and sanitization process. Specialized technicians at our company’s headquarters hand test each device, and only products that pass our rigorous testing receive plug’s Certified Pre-Owned status and are sold.
