When I contacted tech support at Acer for a minor issue, I was shocked to learn, based on my serial number, that the unit I bought is a 2020 model.  It's one-year warranty ran out in November of 2021.  I received it as a new item on March 2, 2022. I paid a geek squad guy to set it up for me & it works very well.  I guess the fact that it was a prior-year model explains why it was so well-priced @600.00. Shocked!
