I ordered this machine before the holidays and it was late arriving due to a shipment delay. But the customer service gave me a small refund to make up for the inconvenience. Then, I the WiFi was spotty with the supplied USB Wifi device. And there was no Bluetooth device.But customer service made up for this again by sending a replacement USB Wifi device and Bluetooth device very quickly. So, yes, so far so good!This machine appears to do everything I'd like it to do so far (though it has an integrated video card, so some games on Steam don't work if they require this). And yes, it really is a 2011 Optiplex 390 that appears to have been refurbished in 2018. But even so, it seems to be a good machine so far. I ordered some additional RAM from the sellers too. All in all, a great deal for the money.
