So, I took a wild chance on this because the price was so low and it was refurbished.  I am replacing a Chromebook in which the AUE (automatic update expiration) date was June of 2022.  I asked the question about this Samsung's AUE and I received no response.  I figured I would buy and just return it if it was unsatisfactory.  After power-up the first thing I did was check the AUE in settings and discovered that it wasn't until JUNE of 2027!!!  That's great news.If you don't know what AUE is and you are buying a chromebook you should probably do some research on this before you make a purchase.  Amazon is literally selling chromebooks with as little as 3 months left until AUE... These are units that did not qualify for the google one-year extension.Anyways, besides the AUE I have tested the sound, screen, keypad... ALL GOOD.  It's obvious that it has been slightly USED, but who cares at the price point.The only remaining test is the battery.  If I can get 4-5 hours out of a full charge that will satisfy my needs.
