Customer Service - Mike - was very helpful to us through this whole process. He was friendly and fast to answer any questions we had. We ordered 3 of these computers. 1 worked great and I haven't had any issues with it yet. The other two would not even try to boot windows. The seller sent replacement hard drives for us to try and see if that would fix the problem, but it did not. The seller has been very helpful and kind through this whole process, but this is a product review and the refurbished computers themselves are not worth buying at this price if 2 out of 3 are faulty.  I gave 3 stars overall though, because the 1 that is working is nice. Small, compact, and runs without lag.
