I wanted a computer to run Fusion 360 and needed real horsepower and good graphics.  This computer has exceeded my expectations .  Works perfectly and looks lightly used.  Battery works well, almost 4 hours while running fusion 360 and watching videos at same time.  This is a heavy weight and heavy duty unit designed for commercial use.  All aluminum case and a really smooth keyboard.  The wifi is amazing in this computer, it has full strength and great speed in the same places my cell phone and chromebook frequently loose connection.
