This recent purchase (12/18/22) is my third identical model Kingdel computer  I bought two in 2019 and now this most recent one. The only difference is this newest model comes with Windows 11 Pro. My wife and I use all three at home, they run all day and we've had zero issues and have never had to call tech support for help. These fanless computers make no noise at all and they are very fast. The 16GB of ram sure helps with fast multi-window browsing and video playback as well as connection to both our company's networks. The bottom line is these are great little computers that do everything our old desktops did at half the price and with complete reliability. Highly recommend
