This unit was obviously used, with some scuffs here and there, but overall in really good shape. It was the 990 as promised, and I had no issues getting it to work. Setup was easy, and I am pleased with the performance for the price. I use it for office applications, and it works just great, a notable improvement over my laptop I have been using. It came with the USB WIFI adapter, as indicated in the product pictures. I do not have any complaints, and decided to order a second one.
