The laptop is like new. The operating system is quick. The feel of the keyboard and touchpad are good. Much better than the older Air even when it was new. The screen is very nice, clear and colorful. The case and screen feel solid and well made. The M1 chip runs the computer quietly. They say it runs cooler so uses less power. Boot up happens in seconds. With intermittent use the battery lasts for days.The 90 day warranty is great from Amazon Renewed. That’s plenty of time to prove it’s going to be good with no defects out of the box.
