The machine's OS stopped working shortly after taking it out of the box.The Seller suggested I should reinstall the OS myself, which meant jumping through a NUMBER of hoops, and spending a LOT OF TIME, in order to fix it.The Seller sent instructions (which were not applicable) and links to videos (which were out-dated).I seem to have managed to fix it, by looking elsewhere online for support.The final straw was their seeming unwillingness to provide the Windows Activation information, (which is normally labelled on the case) for the machine I paid for! (It only took three requests)I *SHOULD* have returned it, but I have spent so many hours to get it working, I feel invested in it now.But I would NEVER buy from this seller, again.Despite their claims, their customer service is poor, begrudging, and not helpful.
