I read all the reviews and had a few concerns, but after receiving the laptop they turned out to be no issue!First, the laptop was well packed and basically appeared brand new!  As an IT professional, I did what I'd normally do with ANY used laptop.  The first was I downloaded Windows 10 Pro, 64bit from Microsoft and created an installation media on a USB drive.  Inserted the drive in the laptop and booted up from the USB by pressing F12.  I chose to do a new install keeping nothing.  Deleted all existing disk partitions.  And proceeded with the install on the unallocated disk space.  Then I proceeded to Windows update and let that update everything.  Next I went to Dell's website for the Lattitude 7280, went to the diganostics and downloaded and ran their Support Assist.  From there I picked to run all the tests.  There were a few more updates, but everything got a pass on the hardware tests.  Finally, I installed Avast & Malwarebytes Antivirus and CCleaner to protect things and keep it happily running!The main concerns I had were the backlit keyboard not working and poor battery performance... I'm happy to report the backlight on mine DOES work, and the battery seems to hold a charge for a good amount of time - like a new laptop should!At $135, this was an absolute steal!!!  I've only had it for a day, but I couldn't be happier... this is EXACTLY what I was looking for!!!
