All I can say is that I am very impressed with the unit that I got. While it is an older laptop, it honestly doesn't feel like it. There are a handful of scratches across the unit that seem to have come with normal wear, but other than that, the unit is near perfect. Battery life is decent for a used laptop, the screen is literally perfect with no scratches on the unit.The speakers are nice and crisp with a nice and heavy bass and are able to easily fill a small room without issue.While I haven't had a lot of time to use the laptop yet, from what I can tell, this is an extremely well built and lasting computer to pick up.For me, while the M1 MacBooks are definitely more powerful, the only other laptop that comes close to the MacBook Pro with the i7 is the M1 MacBook Air, which doesn't have a fan which can cause the computer to overheat with prolonged use. While this won't be able to hit the performance markers that the Air can hit, it definitely does better with staying cool thanks to the built in fans.Add on the ability to run windows through the dual boot, and the value for what is being offered just can't be beat.
