It took 15 minutes to boot up because It was “ preparing windows”. Once that was done, I got a message “ we are unable to sign you out”, and it was very loud. SkyTech customer support ( only available from 9-5)  offered no help just the suggestion to “send it back to us and get a refund in 7-10 business days or call Amazon”. I called Amazon, they shipped out a replacement. With this one ( same make and model as the first)  I was unable to transfer the documents from my old computer to this one because the computer did not recognize the external hard . I called  called Amazon and the rep put me in touch with a rep at Seagate ( the maker of the hard drive). That rep worked with me for an hour and was unable to help so I called SkyTech again. The suggestion this time was,  “ I can walk you through taking the hard drive out of your old computer and putting it into this computer”. After asking him if he was crazy, I hung up, called Amazon and asked for a return label.  I was not expecting a brand new computer, I knew it would be refurbished but I guess you can get good refurbs but in my case that was not true twice. I did purchase a refurbished computer from another seller and that arrives this week. Be sure you read everything and call, ask questions because neither one of these computers had bluetooth capability and I only found that out when I asked the second  SkyTech rep to help me access Bluetooth.
