We have purchased several refurbs of the cf-31 this one by far has been the worse. we had to install drivers. the mouse has never worked. there are other issues as we use it daily that pop up. This also did not even ship until well after the dates given and we were charged well before it was shipped. We can make this work for what we do. So with this review I will say it is a refurb so it should not be prefect. While leaving this review it ask about light weight that is not a far question for this item it is tough-book they are rugged and heavy for a reason.
