There were a lot of bad reviews but for the price couldnt pass it up..Purchased the extended warranty just in case..Took the panel off as soon as I took it out of the box and it is very clean inside with all hardware installed properly and securely..The hard drive and some other components are 2014 so I dont know how long they will hold up..Everything works great so far..It came with a wifi adapter and it was plug and play and works fine..It only has VGA for a monitor but that is no problem for my monitor supports either HDMI or VGA..Adapters are available though..All in all..so far Im very satisfied..Of course you never know with these used machines and usually the windows installation only lasts about a year sometimes not even a year but that is to be expected if you buy a used machine..This one is clean with no scratches dings or loose or missing parts and works well so far..
