Buyer BEWARE!First of all, I am not a person who usually writes reviews and I purchase from Amazon on an almost daily basis. I do, however, take time to read the reviews and usually sort by Most Recent. I am very disappointed in not listening to the experiences of others and thinking that I would "take the chance" on this one. I regret this purchase.When the laptop arrived via FedEx, I immediately opened the package. There was no packaging! The laptop and charger were just inside a box with no filling or anything to keep it from being damaged. Of course, the box was pretty heavily beaten up. This was the first indicator that something would be wrong with the machine. Yet, I pressed on.After unboxing the computer, I tried to turn it on and there was no power. Usually, there would be some type of power on a device but I decided to ignore the second red flag and put the laptop on the charger. It took several hours to get to a place where it was charged, so I thought.Once the computer was charged, I used it for exactly 18 minutes before it powered down the first time. Previous to it powering down, I was going through the process of downloading all the business apps I needed. I confirmed the build of the computer in the System Preferences to ensure I received the actual computer that I paid for. Then, the computer just shut down. At first, I thought this was due to the software (Microsoft 365) install.Again, I put the computer on the charger for quite some time. I tried to turn it back on and it would not power beyond the login screen. It was at this point that I realized I purchased a fast-moving, MacBook Air paperweight! Several times (more than 10x), I tried the process of charging and restarting. Once I could get the computer on, a new error message popped up in the Notifications Center that says: "The battery's capacity is significantly reduced. To restore capacity, please check your service options." What?! This is absolutely insane! The repair of the battery costs more than I paid for the device. Given this serious functional issue, I do not understand how they are selling this for "Refurbished-Excellent" condition. That is a complete lie! It is not in excellent condition if it cannot be used.I have contacted Amazon and they are assisting with receiving a replacement. I am hopeful that the replacement will work!Please look at other options before purchasing from this seller. I have purchased several other MacBook Air computers without any issue and have been extremely satisfied with my purchases. I understand the appeal of wanting a device with a higher Intel package (i7 vs i5), lots more RAM, a larger hard drive, and 2.2 GHz of speed. That would have been great IF the device actually worked but it does not. At best, the computer will stay on for no longer than 30 minutes, while docked and on the charger. Be very careful. Take heed to this advice and the advice of others. Look for other sellers with better ratings and more consistent products. This is not worth one red penny!
