This product worked great....for about 5-6 months.  Now all it does is try to turn on.  Like it takes deep breathes, beeps, repeats over and over.  But never turns on.  Of course, my warranty was for only 3 months.  an extended warranty on a $300 item is not worth it.  And I guess you get what you pay for.  One thing is certain...I will never buy a reburbished item again.  They are a time bomb for trouble.  I only gave this a 2 star rating for the nice 6 months it gave me.  Let's see.  300 divided by 6....$50 a month for use.  Nope.  Never again.It is now March 2022.  This item has been sitting around for awhile.  I finally called the best computer store in the area.  He said get rid of.  Cost more to repair than what I paid for it.  Will do.
