This was purchased to replace a Windows 7 laptop for general use, web surfing etc., because Microsoft keeps sending me scary messages about end of life, though Win 7 does everything I need to do and I know where everything is and how it is named (same went for XP, bless its heart).The interior presented very clean, obviously care had been taken in the refurbishment process.  The components appeared appropriate for the purpose, with one exception: RAM. There are 4 sticks of 2GB each, so total RAM is 8GB as advertised.  However, only two sticks match, and were probably the originals in a 4GB machine, while the other two look like random insertions to meet the spec.  One of them is the same speed as the originals, while the other is higher.  Memtest86 showed zero errors, and in theory all will run at the lower speed (though perhaps not in dual channel), but I was taught not to mismatch RAM and I think that is still a good general rule, so I subtracted one star from a fine machine and transaction due to mismatched RAM.The SmallFormFactor size is nice and compact (Compaq). Cosmetically, the unit appears as new.The DVD burner is a plus for me; most laptops don't include these anymore.Both the VGA and DP video outputs work, though the DP connection through a separately purchased adapter to HDMI is a little wonky, sensitive to just the right insertion pressure.I originally set the machine up using a wired ethernet connection and later added a USB WiFi dongle, which works fine as well.The keyboard works, but I use a different one to which I am more accustomed.  The mouse is actually quite good.Overall I am happy with the purchase from Skytech, which I selected because they had the highest rating among the authorized refurbishers selling this particular machine on Amazon.
