I absolutely love this renewed MacBook Air, I will NEVER ever go back to a pc laptop. In fact, if I could afford a new Macbook I would have gotten one, BUT, this was without a doubt the next best thing. It's beautiful, flawless, looks brand new, came wonderfully packaged, and I was able to easily upgrade the OS to Monterrey. Yes, the battery-life is criminally short, but to me it is worth it overall -- I just make sure I keep it charged, or even plugged in, all the time and personally I'm fine with that: for the hundreds of dollars of savings and all of the plusses and tech specs this item has, a short lived battery is absolutely no problem as a trade off. If I travel, I will simply bring along one of my portable battery chargers that I bring anyway with my current other laptops. I highly recommend this item, and this company.
