Unit is a refurb and did not expect it to be anything else. We bought two units. Packaging was great and the condition of both was also excellent. But where the rubber meets the road - does it work? Well. that's the problem and for all the help we sought it seems nobody can solve the issue. Downloads are atrociously slow to say the least, and all 4 monitors constantly flicker rapidly. Our service is A+, all other computers we have work fine, but no cure for these can be found.
