For the money it is great.I have had it for two days and no problems.It took about an hour to disconnect  my old and get the new running .Windows 10 was up and running as soon as I powered it up. Had to wait for it to up date.I did watch a Utube about pc and Windows 10 the day before.There isn't any paper work with the unit for hooking up.The 10 minute Utube was helpful.I didn't use the keyboard or mouse that came with it.It seems OK used my wireless instead.
