As this Dell Latitude 7490 was only a backup and used very little, perfect condition when I received it, but it  died in 11 months.  Battery life was not good, around 2 hours, and the bottom of this laptop gets very hot while using.  Other than the battery life and the heat issue, you will be very pleased until it dies.  I suspect a Motherboard issue caused by extreme heat in use and then cooling when turned off.  Just a matter of time until you get fractures in the board.
