I wasn't sure what I was getting buying a refurbished Mac. So far it's been fine. Takes a little while longer to boot up than I expected, but I can overlook that considering I got a "new to me" Mac for $500. Wish it had Microsoft Office for Mac...have to use my MacBook Pro for that. No big deal. They sent a standard wired keyboard and mouse with it which was nice of them to do, but I went ahead and order the wireless Apple keyboard and already had the Apple wireless mouse. The 21" screen is really big, glad I didn't go for the larger screen, it wasn't needed. Only reason I rated Tech Support so low as you don't get Tech Support with a used Mac, obviously. I have, however, found Apple Tech Support to be very helpful when I have called them for other  computers I've had. The webcam works well for meetings on Zoom and the sound isn't half bad when listening to music or podcasts. Overall this was a great purchase and I'm happy with it.
