It's rather safe nowadays to offer a lifetime warranty on a product instead of a standard 5-year, 3-year or sometimes 1-2 year warranties. Companies lose absolutely nothing because most users will upgrade their components before the "time-limited" warranties end. So the companies actually make more money by marketing them with lifetime warranties, as 3 or 5 year warranties are rather pointless as the products are obsoleted in this world of fast moving technology.
