*revised after initial review was posted*After installing all my diagnostic software and receiving my data link connector for semi truck diagnostics, I installed drivers and was having a hell of a time trying to connect via USB.  After about two hours of trying everything I assumed a faulty USB board on the toughbook. I tore into it to find the ribbon cable was left unplugged 😡I’ve never purchased a refurbished item before and was quite skeptical. The reviews all seemed great and returning the item was an option if I wasn’t happy so I figured why not give it a try. I still don’t understand how this is a refurbished toughbook. Everything right down to the stylus is in brand new condition, not a scratch or cosmetic flaw anywhere and It even has a screen protector installed. Great laptop for my diagnostic needs, couldn’t be happier
