We bought a refurbished computer because a new computer was not on our list of things to buy at this moment. Operating system works great. The computer is fast and meets our basic needs. Unfortunately, multiple USB ports do not work and the DVD writer door is broken. I guess when it was refurbished these things were over-looked. This will not be a long term computer but it will do for now. We bought refurbished and we knew it was possible that problems would still persist. If you are considering a refurbished computer keep in mind that it is not new and may have issues. I will not be returning it because I need a computer. That simple. The inconveniences are not worth the hassle of returning the product and being without a computer.
