This refurbished unit represents a great value! The unit arrived well packaged and protected, with all necessary accessories (mouse, keyboard and power supply). The outside of the unit is in excellent condition, no scratches or scuffs visible, and the unit is quite clean. Also of note is that a genuine Lenovo power adapter is included, not a third-party unit, very cool. The machine booted up quickly and installed all updates as needed. All accesories functioned well, and I have had no problems with any of the included ports, and I have four of the available USB ports occupied. I use the machine primarily to run a security suite of cameras, and the unit works flawlessly for this purpose. Even with this software running, using other programs at the same time does not slow it down. I am very pleased with this unit.
