I was a little concerned after reading the discrepancy between the  good and bad reviews.  Then found that even new computers, across almost all brands, had about 15% 1-star ratings as well.  So instead of looking at the computer itself, I looked at the actual companies offering this HP system.  Maybe the supplier was the issue.Looking at it that way, I went with the highest rated supplier (TecRefurbs - 99% 5-star with thousands of reviews).  I paid $10 more than the lowest price, but they delivered a super clean machine, with zero obvious damage inside and out, several days earlier than promised.  I used the monitor, keyboard, mouse and wireless printer from my 9-year-old HP system and everything worked at startup.  I'm keeping the provided keyboard and mouse as backups, so can't speak to their reliability.  Windows 10 was installed as promised and activated with no issues.  My Carbonite download brought back all my  old docs, photos, videos and music and this system is still much faster than my old setup.  I'm not a heavy gamer or streamer, so I don't need a huge amount of speed or memory.  After a week of use, the system is still running fast and fine.  It works for me and I saved some money in the process.
