It's a superb scent, great lasting power and sillage. However, it seems to share one odd characteristic among many of its fans here, which was commented upon in another posting - we really like it and think it's great - but we don't wear it all that much.
It's supposedly been discontinued for a few years now, and it went pretty cheaply everywhere around the world a couple of years back. Certainly worth an investment if you find it cheap.
If you do buy it, make sure that you never go and smell Salvatore Ferragamo Pour Homme. It's a more interesting fig leaf scent, and after you've smelled it, when you again smell Good Life, it suddenly seems incomplete.
