I've had almost 2 years on this refurbished laptop.  I have owned several 1k+ laptops over the years and this has ran everything they could without hiccup (several simultaneous GPU intense programs).  It even survived a drop from a railing and subsequent fall down a flight of stairs onto tile, it was unscratched.  The battery life is still several hours.  The current price is even less than I paid 2 years ago, I am considering buying another as a backup.
