I’m not a computer geek.  Just an old guy doing email, buying stuff and a lot of photo management on a computer .  I was always a little suspicious of the “renewed” electronics items.  This is the first one I’ve ever purchased.  This machine is such a pleasant surprise. Fast computing power, all metal case...and the keyboard.  Wow, what a keyboard...solid, positive and well lit.  The battery lives a long time between charges.  This Computer is a fantastic value.  It does weigh a bit more than other less “industrial “ designs.  I highly recommend this computer
