I’m amazed that this Dell has lasted this long, especially at this inexpensive price. I was expecting a 1-2 year window before it broke down. I have not had to contact tech support nor have I had any crashes. Window Updates were automatic until Microsoft stopped issuing for this model. A plus, Microsoft Windows Security Scan continues to scan and send weekly reports. If I had to nitpick, I have two minor issues. One, is if you’re using a lot of usb dongles, you’ll need an external usb hub. Secondly, no Bluetooth, so plan on getting an adapter. The seller is an authorized Dell refurbisher which makes buying this a no-brainer for a Dell at this price point.
