Solid performer. Instructions for activating the installed Windows 10 are good. It comes supplied with a USB WiFi external antenna which is flimsy and offers a poor signal. When installed on the back amongst the tangle of cables it does not get full bars from the router which is less than 12 feet away, in the same room; required moving the antenna to the front of the unit, away from all cables [replaced with a better antenna].This unit is refurbished, but shows no signs of wear. The unit utilizes a SSD drive, which improves effective "speed".I'm very happy with the unit; wish it came with an internal WiFi antenna [4 stars for the cheap USB antenna]. Also wish it came with an internal Bluetooth but since there is an abundance of USB ports, purchasing a Bluetooth dongle isn't a major issue.
